CM90BF Fixed-Frequency Oil-Free Screw Air Compressor

CM90BF: catalogue air-compressor data; 0.8 / 1.0 / 1.25 MPa; FAD 16.30 / 14.52 / 12.30 m3/min; 90 kW. Kept as draft pending verified public model media and current commercial confirmation.

Description

CM90BF is the largest fixed-frequency lower-pressure model in this selected set. The catalogue records 16.30, 14.52 and 12.30 m3/min FAD at 0.8, 1.0 and 1.25 MPa, plus 90 kW motor power and 73 dB(A). Its role on the site is to give buyers a fixed-output reference beside the CM90PVF variable-frequency entry.

Baseload Decision

Use CM90BF as a candidate only after separating baseload from intermittent peaks. If the plant normally operates near a stable demand, the fixed configuration may be worth quoting; if demand moves through a broad range, request a CM90PVF comparison. The website does not choose between them without operating data.

Pressure Assumption

At this capacity, a poor pressure assumption can materially change the comparison because the documented FAD is different for each pressure class. Confirm downstream losses and the minimum acceptable pressure at critical equipment before selecting the catalogue row used for sizing.

Cooling Footprint

The table lists 3870 kg and 3750 x 1850 x 2180 mm for air cooling, versus 2160 kg and 2500 x 1400 x 1580 mm for water cooling. Verify floor loading, access route and utilities for the exact quoted option.

System Sequencing Review

A larger fixed-frequency compressor may operate alone or within a multi-compressor header, but the catalogue does not state the intended plant sequence. If other units are present, list their capacities, pressure settings, control method and normal operating order. Explain which machine is expected to carry base load and which equipment covers peaks or standby duty. This system-level information helps prevent a buyer from judging CM90BF only by its maximum catalogue FAD and creates a clearer basis for comparing fixed and variable-frequency alternatives under the same site conditions.

Standby Philosophy

For a multi-unit station, record the present header control method and which machines are normally unavailable during planned maintenance. This creates a clearer redundancy discussion than simply adding installed nameplate capacities. Tell the supplier whether the proposed unit is intended for base duty, trim duty, standby service or temporary redundancy during maintenance. The intended role changes the questions that should be asked about sequencing and reserve capacity. This website does not assign that role from model size; it must come from the plant operating philosophy and the confirmed quotation.

How does CM90BF differ from CM90PVF in the source?

CM90BF is presented with fixed FAD values, while CM90PVF is presented with FAD ranges for the same three pressure classes.

Is 16.30 m3/min valid at 1.25 MPa?

No. The source associates 16.30 with 0.8 MPa and 12.30 with 1.25 MPa.

Why is this product still draft?

Verified public model imagery and current commercial confirmation have not yet been assigned to the website record.

CM90BF source limit: The figures above remain catalogue air-compressor evidence for CM90BF. The CM90BF draft should not be used to infer acetylene approval, immediate availability, site-specific guarantees or the equipment options fixed by the eventual contract.
