CPV, CPV/ATEX corrosion-resistant centrifugal fans of polypropylene / antistatic plastic
Country: · Model: CPV, CPV/ATEX
CPV is a single-inlet centrifugal fan whose casing and impeller are molded from polypropylene, so aggressive gases and vapors do not corrode it. The CPV-720 … CPV-2045 range gives up to ~10 500 m³/h at an air temperature from −25 to +70 °C. There is also an explosion-proof version, CPV/ATEX, made of antistatic plastic.

Description
The plastic flow path is corrosion-resistant by itself, so nothing needs to be painted. The impeller blades are forward-curved. The insulation class F motors run on ball bearings, IP55, three-phase 230/400 V 50 Hz up to 4 kW and 400/690 V 50 Hz above 4 kW, and the CPV range is made with 2, 4 and 6 poles. In CPV/ATEX the casing and impeller are made of antistatic ATEX plastic, which does not accumulate electrostatic charge. The fans are certified for categories 2G or 2D, and the motors have a flameproof enclosure Ex db (II 2G Ex h IIB T4 Gb), increased safety Ex eb (II 2G Ex h IIB T3 Gb) or protection against dust ignition Ex tb (II 2D Ex h IIIC T135 °C Db) with built-in PTC thermistors. The models CPV/ATEX-815 … CPV/ATEX-1630 give up to 8000 m³/h at an air temperature from −25 to +60 °C.
How to choose
For ordinary extraction of aggressive gases without explosion risk CPV is taken, which is stronger in airflow and tolerates +70 °C. If an explosive atmosphere may appear in the airstream, for example in an area with solvents, CPV/ATEX is needed, with an airflow of up to 8000 m³/h and an air temperature of up to +60 °C. The type of explosion protection of the motor is chosen according to the environment. Ex db or Ex eb for gases, Ex tb for combustible dust. On request, a version for combustible dust and protection higher than standard are made.

FAQ
What environments are CPV fans suitable for?
For extraction of aggressive gases and vapors in galvanizing and pickling areas, in chemical fume cupboards, scrubbers and in acid and fertilizer production.
What is the permitted air temperature for CPV and CPV/ATEX?
CPV works from −25 to +70 °C, and the explosion-proof CPV/ATEX from −25 to +60 °C.
Does the CPV casing need to be painted?
No, corrosion protection is provided by the polypropylene itself, and no coating is needed.
What is the airflow of CPV and CPV/ATEX?
According to the datasheet the CPV-720 … CPV-2045 range gives up to ~10 500 m³/h, and CPV/ATEX-815 … CPV/ATEX-1630 up to 8000 m³/h.
What is the power supply of the motors of these fans?
Three-phase 230/400 V 50 Hz up to 4 kW and 400/690 V above 4 kW, protection class IP55.
