CMP, CAS medium- and high-pressure centrifugal fans (small series), up to 45 kW
Country: · Model: CMP, CAS
CMP and CAS are small-series direct-drive centrifugal fans, with CMP for medium pressure and CAS for high pressure. Motors go up to 45 kW, and the CMP model line runs from CMP-38 to CMP-2050. They are installed in compact extraction and process systems where pressure is needed at moderate airflow.

Description
The CMP casing is sheet steel, and for models 38-2M and 380 it is unpainted cast aluminum. The impeller is galvanized steel with forward-curved blades. The air must be from −25 to +120 °C, for 38-2M and 380 up to +100 °C, and versions up to +250 °C are made on request. According to the datasheet CMP has a power of 1.1–15 kW and an airflow of up to 16 500 m³/h. In CAS the casing is steel and the impeller blades are backward-curved, while for models 242, 248, 254, 260, 640, 645 and 650 the impeller is cast aluminum. The air temperature is the same, from −25 to +120 °C, and up to +250 °C on request. There is no separate datasheet for CAS, and the range CAS-242 … CAS-1090 with 2-pole motors of 0.37–45 kW and an airflow of up to 12 000 m³/h is taken from the datasheet of the CAS/ATEX version. The motors are class F, IP55, and the coating is polyester, polymerized at 190 °C.
How to choose
First determine the required pressure. For moderate network resistance CMP is taken, and for high resistance one moves to CAS. Single-phase 230 V supply is available only for some CMP models, while three-phase 230/400 V applies up to 4 kW and 400/690 V above 4 kW. For aggressive air stainless steel is made on request, and for explosive atmospheres of category 2 there are CMP/ATEX and CAS/ATEX. Related series are CMA and CA of cast aluminum, CAS-S with a silencer, CAM, CMPE and CRL.

FAQ
How does CMP differ from CAS?
CMP is designed for medium pressure and has an impeller with forward-curved blades, while CAS is for high pressure with an impeller with backward-curved blades.
What is the maximum air temperature for CMP and CAS?
Standard up to +120 °C, and for CMP models 38-2M and 380 up to +100 °C. Versions for air up to +250 °C are made on request.
What are the power and airflow of the CMP and CAS ranges?
CMP according to the datasheet 1.1–15 kW and up to 16 500 m³/h. The CAS range in the ATEX version covers 2-pole motors of 0.37–45 kW and an airflow of up to 12 000 m³/h.
Are there single-phase fans in this series?
Yes, some CMP models have a 1~ 230 V supply. The rest work from a three-phase 230/400 V 50 Hz supply.
Are these fans made in an explosion-proof version?
Yes, for zones with an explosive atmosphere there are CMP/ATEX and CAS/ATEX with category 2 certification.
