Pneumatic Breaker Package RFQ: Compressor, Hose, Lubricator, Chisel, and Spare Kit Checklist

A complete pneumatic breaker RFQ should specify the whole operating package, not only the breaker body. The buyer needs a confirmed breaker model and application, compressor airflow basis, pressure at the tool while working, hose and coupling arrangement, moisture control, the model-correct lubrication method, compatible chisels, initial spares, documents, and packing scope. There is no universal package: air demand, allowed pressure, hose size, oil grade, shank geometry, and retainer design are model-specific and must be confirmed against the current manufacturer manual.

This guide is for mines, quarries, contractors, distributors, and industrial procurement teams preparing an enquiry or purchase order. It explains what information to exchange so that the delivered system can be commissioned without discovering a missing hose, wrong coupling, incompatible chisel, or unsuitable air source. It does not replace the selected breaker’s operating manual, compressor sizing calculation, or local safety rules.

What belongs in a complete pneumatic breaker package?

The practical boundary is everything required between the compressor outlet and the point where the chisel enters the work. A supplier may quote some items as standard, some as optional, and some as buyer-supplied. The RFQ should make that boundary explicit.

Step 1: Define the job before naming the breaker

Start the RFQ with the work, because the same tool description can hide very different operating conditions. State whether the task is concrete demolition, secondary rock breaking, trenching, scaling, asphalt cutting, or another defined use. Describe the material as observed on site rather than relying only on labels such as “hard rock.” Include reinforcement, discontinuities, weathering, confinement, access, and the required finish where relevant.

Also record the working position and handling constraints. A vertical floor-breaking task, horizontal wall work, and overhead scaling do not impose the same ergonomic and retention requirements. State the expected shift pattern, typical continuous operating interval, number of tools that may run together, ambient temperature range, altitude if it affects the compressor, and whether the hose must pass through long galleries or around multiple bends.

If the breaker itself has not been selected, use the decision factors in How to Choose a Pneumatic Breaker for Concrete and Rock. Ask the supplier to identify assumptions instead of accepting a model recommendation without an application boundary.

Step 2: Specify compressor capacity on a comparable airflow basis

A compressor nameplate and a breaker catalogue can use different airflow conventions. “CFM” alone is incomplete because the stated volume can refer to free-air delivery, a standardized reference condition, or actual compressed volume at another pressure and temperature. The RFQ should state the rating basis and units for both the available compressor and the breaker demand.

For a shared compressor, list every tool that may operate simultaneously. The sizing check must include the combined demand, the compressor’s deliverable output at the required condition, distribution losses, and the site’s altitude and ambient conditions. Do not add a universal reserve percentage: the appropriate margin depends on compressor control, duty cycle, leakage, future demand, and the manufacturer’s sizing method.

Ask for confirmation of:

• the breaker’s required airflow and allowed inlet-pressure range;
• the compressor’s rated output and the standard or reference conditions behind that rating;
• the maximum number of breakers intended to operate at once;
• the regulator, receiver, manifold, and any other large pressure-loss points;
• the method used to verify pressure at the tool while it is actually hammering.

For terminology and conversion risks, see SCFM, ACFM, and FAD in Rock Drilling.

Step 3: Treat hose and couplings as part of the performance specification

A breaker can receive acceptable static pressure yet lose power under load because the hose, fittings, or manifold cannot pass the required flow. Record the total hose length from the distribution point to the tool, the hose inside diameter, the number of joints, and every coupling or adapter. Ask the supplier to approve the complete arrangement for the chosen breaker rather than approving each component separately.

The purchase specification should also define coupling type, thread form, sealing method, material, working-pressure rating, and the positive retention method required by the site. Mixing nominally similar regional coupling systems is a common commissioning failure. Photos help during an enquiry, but controlled names and dimensions should govern the order.

Where United States construction rules apply, OSHA requires pneumatic tools to be positively secured to the hose, requires retainers on percussion tools, and sets specific provisions for larger air hoses and component pressure ratings. Other jurisdictions may use different requirements. The buyer should identify the governing site standard in the RFQ rather than assuming a supplier’s default connection is acceptable.

Step 4: Define moisture control and lubrication by exact model

Compressed air carries water and contamination that can disturb operation, promote corrosion, wash away lubricant, or contribute to freezing in cold conditions. Ask where condensate is removed, how the separator is drained, and whether the compressor or site network already includes aftercooling and moisture control. The final arrangement must suit the actual climate and hose run.

Lubrication is not universal. Some breakers have a built-in oil reservoir; other models require a constant-feed inline lubricator. Ingersoll Rand’s paving-breaker instructions, for example, distinguish between models with built-in lubrication and models that need an inline device. Atlas Copco’s maintenance guidance likewise tells operators to check hose and couplings and to maintain model-appropriate lubrication. These sources support the control principle, not a substitute oil or setting for an unrelated model.

The RFQ should therefore request:

• lubrication method for the exact breaker model;
• approved lubricant specification for the expected temperature range;
• lubricator model, capacity, connections, and adjustment method if external;
• location of the lubricator in the air line;
• daily and periodic maintenance instructions;
• water-separator type, drain method, and replacement elements if applicable.

Step 5: Lock chisel and retainer compatibility with dimensions

“One moil and one flat chisel” is not enough. A working tool must match the breaker’s chuck and retainer geometry. Ask for shank cross-section, shank length, collar or notch form, guide diameter where applicable, and the supplier’s controlled tool reference. State the desired working-end profile and overall length separately.

Do not approve interchangeability from brand or model nickname alone. A controlled drawing, sample comparison, or supplier-signed compatibility statement is safer than a verbal “fits the same machine” claim.

Step 6: Build an initial spare and consumable kit from the parts list

The first-order kit should support commissioning and the planned operating interval, but it should not be a generic bag of seals. Ask for the current exploded view and parts list, then agree which items are operator-replaceable and which require trained service personnel. Separate breaker spares from air-line consumables and chisel stock.

Typical categories to discuss include retainers and their pins or springs, model-specific seals, lubricator service items, water-separator elements, approved couplings, short hose assemblies, and the working tools that experience normal wear. Quantities should be based on fleet size, duty, lead time, local service capability, and supplier recommendations.

Use the more detailed identification workflow in Pneumatic Breaker Spare Parts RFQ. The package RFQ should reference the same breaker model revision so the machine, BOM, and spare kit cannot drift apart.

Step 7: Control documents, inspection, and packing

Ask for a package-level bill of materials that states included, optional, and buyer-supplied items. The breaker serial or batch identification, chisel references, hose lengths, coupling standards, lubricator and separator models, spare quantities, and manuals should all appear in the same order file.

For pre-shipment approval, request clear photos of the assembled package, interface measurements for critical connections, the breaker identification, and a functional-test record defined in the purchase order. A no-load demonstration does not prove the full compressor-to-tool system will perform at the buyer’s site, so the record should state the air source and test conditions used. Do not request certificates that are irrelevant to the contract or cannot be traced to the supplied lot.

Packing instructions should separate sharp working ends, protect hose and threaded connections from contamination, identify cartons by package BOM line, and preserve manuals and small spares in a traceable container. For export orders, state the required shipping marks, document language, and destination-specific packaging rules.

Common purchasing mistakes

• Ordering by breaker weight alone. Handling class does not prove air-source or chisel compatibility.
• Accepting “CFM” without a basis. Airflow values cannot be compared reliably until reference conditions are known.
• Checking only compressor outlet pressure. The pressure available at a hammering tool may be lower after distribution losses.
• Using a universal hose package. Length, inside diameter, fittings, ratings, and site rules must be checked together.
• Assuming every breaker uses the same lubricator. Built-in and inline arrangements differ by model.
• Describing chisels only by tip shape. Shank and retainer geometry control compatibility.
• Buying an untraceable spare kit. Parts should map to the current exploded view and model revision.

Frequently asked questions

What compressor information must be included in a pneumatic breaker RFQ?

Provide the compressor model, rated output, airflow rating basis, regulated pressure, site altitude and temperature where relevant, and the number of tools that may run simultaneously. Ask the supplier to confirm pressure and flow at the tool under load after the proposed hose and fittings.

Does every pneumatic breaker need an inline lubricator?

No. Some models use a built-in reservoir, while others require constant-feed inline lubrication. The selected breaker’s current manual must define the method, lubricant, and maintenance routine.

How should hose length and inside diameter be specified?

State each hose section, total route length, inside diameter, rating, coupling type, and manifold or adapter count. Ask the supplier to approve the whole distribution path for the breaker’s required flow; a universal diameter rule is not reliable.

What chisel details prevent a compatibility error?

Control the shank cross-section, shank length, collar or notch, retainer interface, guide diameter where applicable, working profile, and overall length. Use a drawing or measured approved sample rather than model nickname alone.

What should be in the first spare kit?

Base it on the exact model’s parts list, fleet size, duty, service capability, and replenishment lead time. Separate breaker spares, air-line consumables, couplings/hoses, and working tools, and identify every item by a controlled part reference.
