Use the interactive sizing worksheet to prepare a record with your values. It can export incomplete records while you collect the missing information.

Questions for the quotation

  1. What exact model and SKU does this quote cover?
  2. Which document and revision support its flow and dew-point ratings?
  3. What capacity will it deliver at the stated pressure, inlet temperature and room temperature?
  4. Does that calculation use the same flow reference as the compressor data sheet?
  5. What pressure dew point will it maintain at those conditions?
  6. Which filters, drain arrangements, adapters and electrical provisions does this package require?
  7. What maintenance and consumables does the supplied manual specify?
  8. What pressure loss should be allowed for this arrangement?

Ask the supplier to return the completed answers with the quotation. A higher nominal flow value alone does not close the unanswered questions.

Compare the answer with the record

Check that the quoted SKU agrees with the model reference and that its power supply matches the proposed installation. Keep any changed specification with the quotation date and source revision. Report a discrepancy through contact and corrections.
