CMN CMW direct-drive oil-free scroll — pressure and module variants — CMN / Xinmaien Technology (Taizhou)

Datasheet

Product overview

Power: Selected single2.2/3 kW; multi4 ×3.7 or6 ×4.5 kW · Pressure: Distinct0.8 /1.0 /1.2 MPa suffixes · Flow: CMW2.2:255 vs215 L/min by pressure version

CMN's CMW family uses oil-free scroll airends directly driven by permanent-magnet motors, with single and multiple-airend arrangements. The manufacturer describes pressure, warning and maintenance indications and a larger touchscreen for packages with three or more airends. Actual controller options, module staging and fault/isolation behavior should be confirmed for the supplied version.

The table preserves different pressure suffixes. CMW2.2-0.8 lists 2.2 kW, a 0.2–0.8 MPa pressure range and 255 L/min; CMW2.2-1.0 lists the same motor rating with 0.2–1.0 MPa and 215 L/min. CMW3.0-1.2 instead lists 3 kW, 0.2–1.2 MPa and 210 L/min. The comparative advertising text's 262 L/min is not substituted for the detailed 255 L/min row. Obtain the complete capacity-rating pressure and volume-reference conditions rather than assuming constant flow across the stated pressure range.

Selected multi-airend rows are CMW7.4-0.8: two 3.7 kW motors, 830 L/min; CMW15-0.8: four 3.7 kW motors, 1660 L/min; and CMW27-1.2: six 4.5 kW motors, 2160 L/min. The original cabinet image is labelled CMW15 without a readable pressure suffix and is a family view. CMW15-0.8 lists 1400 × 800 × 1280 mm, 350 kg and a 1-inch outlet; CMW27-1.2 lists 1400 × 800 × 1870 mm, 650 kg and a 1-inch outlet. Cabinet dimensions do not include service or cooling clearances.

Provide the base/peak consumption, operating cycle, installation/supply conditions and required output during maintenance. Request actual sequencing, module running-hour rotation, protection and isolation details and the available flow with a module out of service; it is not a proven proportion of the catalogue capacity. Specify moisture, particle and oil limits, dryer/filter scope, drains and air-quality sampling. The site's medical and laboratory application wording and Class0 claim are not complete medical or breathing-air approval. Obtain current model-scoped reports, drawings, manuals, wear-part intervals, delivery tests and commissioning/support terms. Noise-column figures lack full measurement conditions and are not guaranteed room sound levels.
