CM45PVF Variable-Frequency Oil-Free Screw Air Compressor

CM45PVF provides a mid-size variable-frequency comparison point in the 0.8 / 1.0 / 1.25 MPa oil-free table. Its FAD ranges are 3.12-7.80, 2.45-6.13 and 2.26-5.65 m3/min respectively. The catalogue also lists distinct air-cooled and water-cooled package weights and envelopes.

CM45PVF Data

Pressure First Selection

A buyer should first lock the required pressure class, then compare the corresponding minimum-to-maximum flow band with measured plant demand. This order prevents a common spreadsheet mistake: pairing the 7.80 m3/min upper figure with a 1.25 MPa requirement even though the source table associates a different range with that pressure.

Cooling Utility Check

Cooling utility availability can change the practical installation choice even before commercial evaluation. The air-cooled row is listed at 1930 kg and 3040 x 1280 x 1800 mm, while the water-cooled entry is 1430 kg and 2200 x 1350 x 1530 mm. Confirm which variant the quotation covers.

Retrofit Measurements

For retrofit work, record doorway sizes, equipment-room access and existing cooling-water quality or ventilation capacity. The catalogue dimensions help screen feasibility but do not replace final connection drawings or maintenance-clearance requirements.

Retrofit Utility Survey

A retrofit enquiry benefits from a short utility survey before a model is nominated. Note the available electrical supply, cooling-water availability and quality if water cooling is considered, ventilation path if air cooling is preferred, access restrictions, and the location of existing dryers and filters. Also identify the pressure measured at the current compressor and at the critical point of use. Those measurements can reveal distribution losses that should be included in the selection basis rather than hidden inside a generic pressure target.

Existing Room Constraints

Create a simple equipment-room constraint list before requesting a final layout: available floor rectangle, service side, overhead restrictions, drainage, ventilation route and cooling-water tie-in points. Photograph the access route, note door and aisle dimensions, and mark nearby heat sources or water connections on a simple room sketch. A dimensional screen can then be performed against the correct cooling variant before detailed engineering starts. This is especially useful when the replacement location cannot be expanded and the air-cooled and water-cooled envelopes differ materially.

CM45PVF source limit: The figures above remain catalogue air-compressor evidence for CM45PVF. Nothing in the CM45PVF draft verifies acetylene compatibility, inventory position, guaranteed site performance or the final configuration shipped under a purchase order.
