Description
CM45BF is the 45 kW fixed-frequency row used for a mid-range lower-pressure comparison. Its source values are 7.80 m3/min at 0.8 MPa, 6.13 at 1.0 MPa and 5.65 at 1.25 MPa, with a listed noise value of 68 dB(A). The page keeps those pressure-specific flows intact instead of collapsing them into one capacity number.

Control Option Compare
For a production line with relatively repeatable compressed-air demand, compare the appropriate CM45BF FAD value with measured consumption and reserve. For a line that changes substantially by shift or season, include CM45PVF in the commercial review rather than assuming the fixed or variable approach will automatically be better.
Pressure Class Risk
The key procurement risk is comparing models at different pressure classes. A 0.8 MPa FAD should not be set beside a 1.25 MPa requirement without correction. Record the required pressure at the point of use and estimate distribution losses before requesting a model recommendation.
Room Fit Check
Air-cooled data is 1930 kg and 3040 x 1280 x 1800 mm; water-cooled data is 1430 kg and 2200 x 1350 x 1530 mm. These values support early equipment-room checks, while connections, clearance and foundations require the approved project drawing.
Production Schedule Review
When evaluating a fixed 45 kW row, describe the production calendar that creates the compressed-air load. Separate weekday base demand, shutdown periods, sanitation or maintenance windows, and any short process peaks. The purpose is not to predict savings on this page; it is to give the supplier enough context to decide whether a fixed-output configuration should be quoted alone or beside a variable-frequency alternative. A schedule-based RFQ is more useful than a single maximum-flow number because it shows how the compressor would actually be asked to operate.
Demand Verification Method
Separate production air from maintenance or cleaning use when those loads occur at different times. This avoids combining every possible consumer into one unrealistic simultaneous-demand case. Where possible, base the enquiry on logged flow or compressor-loading data rather than a nameplate total of connected pneumatic equipment. If measurements are unavailable, document simultaneous-use assumptions and identify which loads are intermittent. The supplier can then challenge the estimate during technical review instead of treating a rough connected-load sum as measured consumption.
Which CM45BF FAD belongs to 1.25 MPa?
The source shows 5.65 m3/min for the 1.25 MPa class.
What should be kept constant in a BF versus PVF comparison?
Use the same required pressure, demand profile, air-quality target and site utilities.
Can the catalogue outline replace a GA drawing?
No. Use it for screening and obtain the confirmed general-arrangement drawing before construction.
CM45BF source limit: The figures above remain catalogue air-compressor evidence for CM45BF. Acetylene duty, stock, warranted operating performance and final CM45BF order configuration remain outside the evidence contained on this draft product page.
