A breathing air compressor quotation is only as useful as the information used to prepare it. A short request for a “high pressure compressor” can leave major questions unanswered: which cylinders will be filled, what pressure is required, how often will the system run, what power is available and what air-quality process applies? This RFQ template turns those questions into a concise specification that suppliers can use to propose comparable equipment.
Why an RFQ template is better than a model-only enquiry
A model number can be a helpful starting point, but it does not define the operating conditions. Two facilities can require the same final pressure yet need different output, mobility, filtration, filling accessories and service support. A structured RFQ gives suppliers the evidence they need to recommend the correct platform and helps the buyer compare what is included in each response.
For a full technical buying checklist, begin with the breathing air compressor specifications guide. Use this page when the next step is to turn those decisions into a clear request for quotation.
1. Define the application and the cylinders
State the intended application: diving, SCBA, marine, industrial, project work or another clearly defined use. Then list the cylinder types, water volume, number of cylinders and normal starting pressure. Confirm the required final pressure from the cylinders and operating procedure. This prevents a supplier from making assumptions about whether the programme is 200, 300, 350 or 450 bar.
Where the pressure choice has not been finalised, compare the 300 bar and 350 bar compressor requirements before asking for a final configuration.
2. Describe the expected filling workload
Record the expected fills per day or shift, peak demand, acceptable waiting time and whether the work is occasional, regular or continuous. This lets the supplier discuss an appropriate flow rate in litres per minute and the right working pace. It also shows whether portability or a dedicated stationary installation is more suitable.
For example, a buyer seeking a 300 L/min 350 bar platform can review the B25H30 high pressure compressor. A regular higher-volume programme may need a stationary capacity discussion around the B68V68 stationary compressor. The RFQ should still include the workload, because listed output does not explain the complete job.
3. Provide power and installation information
Include the local voltage, frequency, phase where relevant, indoor or outdoor location, available space, ventilation and service clearance. If the unit will travel to a field site, add the transport route, field power availability, setup space and weather protection. These details affect the practical configuration and help prevent delays after delivery.
When the same system has workshop and occasional field responsibilities, use the workshop and field-use configuration guide to make both working patterns clear in the enquiry.
4. Specify the air-quality and filtration process
State the required application, the intended intake location, filtration expectations, drain practice, consumable plan and quality-verification requirement. The operator must follow the requirements that apply to the location and use. Including these subjects in the RFQ gives suppliers a better basis for proposing compatible accessories and documentation.
Buyers can review relevant certificates and reports alongside the final model proposal. The high-pressure compressor maintenance checklist is useful for defining the handover, consumables and ongoing support expected after commissioning.
5. List the accessories and project documents needed
State whether the quotation should include filling hoses, panels, connectors, storage, transport equipment, spare parts, manuals, test documents, commissioning support or operator training. Requesting these items at the beginning makes the delivered scope easier to compare and avoids hidden gaps between technical proposals.

Use the completed template to compare proposals
Send the same completed specification to each supplier, then compare the proposed pressure range, flow, included equipment, installation assumptions, documentation and service scope. This produces a more reliable decision than comparing a price and a headline pressure figure alone. Send the completed RFQ to BUENAIR to discuss an appropriate breathing air compressor configuration.
