Description
The impeller suits clean or slightly dusty air, and the sheet steel casing has an anti-corrosion polyester finish. The small-series CMR works with direct drive, with sizes from CMR-1031 to CMR-2380, 2-pole, 4-pole and 6-pole versions, a power of 0.75–22 kW and air of −25…+120 °C. In CMRS the impeller sits on the motor shaft, the casing is continuously welded, an inspection and cleaning hatch is provided from size 630, sizes are 350–1400, power is 0.37–110 kW, and the standard air temperature is −25…+90 °C. CMRS-X has a belt drive with the motor on a pedestal with tensioning slide rails and a set of pulleys, belts and guards to ISO 13857. CMRS-X/R-F-400 is designed for smoke extraction at 400 °C/2 h outside the fire zone (EN 12101-3, certificate No. 0370-CPR-6773) and continuously handles air up to +120 °C. The motors are class F, IP55, IE3, and IE4 for 75–200 kW, with a supply of 230/400 V 50 Hz up to 4 kW and 400/690 V 50 Hz above 4 kW.
How to choose
Air up to +250 °C in CMR or up to +150 °C in CMRS requires a made-to-order version, special versions go up to +300 °C, and stainless steel is also available. For explosive atmospheres CMR/ATEX is made, and CMRS is available in ATEX category 2 and in arrangements such as ARR.8. The series are taken for aspiration, process ventilation, extraction from production rooms and systems with high resistance of ducts and filters. If the air is heavily dusty, look at the heavier series CAMA, CAMC and CAMD.

FAQ
How does CMR differ from CMRS?
CMR is the small series with direct drive, 0.75–22 kW and up to 48 000 m³/h. CMRS is the large one, 0.37–110 kW and up to 173 400 m³/h, with a continuously welded casing.
What air temperature is permitted?
For CMR from −25 to +120 °C, for CMRS from −25 to +90 °C. On request up to +250 °C and +150 °C respectively, and special versions up to +300 °C.
Is there a belt drive and a version for smoke extraction?
Yes, CMRS-X has a belt drive. CMRS-X/R-F-400 is intended for smoke extraction at 400 °C/2 h outside the fire zone, certificate 0370-CPR-6773.
For what kind of air is the impeller suitable?
For clean or slightly dusty air. For dusty air with granular material the heavier series CAMA, CAMC, CAMD is better.
What is the energy efficiency class of the motors?
IE3, and for powers of 75–200 kW IE4. The motors are class F, IP55.
