Description
CM22BF is the fixed-frequency counterpart at 22 kW in the lower-pressure oil-free family. The source gives discrete FAD values of 3.50, 3.13 and 2.61 m3/min for the 0.8, 1.0 and 1.25 MPa classes. Unlike the PVF page, there is no variable FAD range published for this BF row.

Steady Demand Test
This model is best evaluated from a steady-demand question: does the facility regularly need a flow close to the confirmed fixed operating point, and what happens during lower-demand periods? If the load varies widely, ask the supplier to compare the BF configuration with CM22PVF using the same pressure class and operating schedule.
Energy Claim Boundary
A fixed-frequency catalogue row should not be turned into a variable-load savings claim. The website deliberately avoids predicting energy use because no measured plant profile or project efficiency calculation has been supplied. Use the RFQ to request a like-for-like comparison.
Cooling Variant Data
The source lists both cooling arrangements: 1000 kg with a 1900 x 1000 x 1635 mm air-cooled outline, or 850 kg with a 1680 x 1000 x 1335 mm water-cooled outline. Keep the cooling choice attached to every layout document.
Fixed Duty Questions
For a fixed-frequency candidate, record how often the plant is expected to operate below its normal demand and whether another compressor, receiver or process buffer already handles short fluctuations. The public page does not assume a specific sequencing strategy. Give the supplier the operating schedule, existing compressor arrangement, receiver volume if relevant, and any limits on starts or unloaded operation that the owner applies. This information supports a project comparison without making an unsupported efficiency or control claim from the catalogue row.
Receiver And Header Data
If an existing plant has pressure complaints, record where and when they occur before assuming the compressor itself is undersized. A restriction, filter condition or distribution loss can change the selection question. Include the existing receiver size, header pressure range and major intermittent consumers when these are known. They can influence how a fixed-frequency machine participates in the system, even though the catalogue row itself contains no receiver-sizing instruction. Recording these facts also gives commissioning teams a traceable selection basis without publishing operating setpoints on the website.
What does BF mean on this website?
It labels the fixed-frequency oil-free family transcribed from the approved catalogue.
Should CM22BF be compared with CM22PVF?
Yes when demand variation may influence the preferred control approach; use the same pressure and duty profile for comparison.
Is an energy-saving percentage published here?
No. The page avoids project savings claims without site data and a confirmed calculation basis.
CM22BF source limit: The figures above remain catalogue air-compressor evidence for CM22BF. The CM22BF source does not prove acetylene duty, on-hand availability, guaranteed installation performance or the exact specification attached to a future order.
