PF, PF/EC, CJPF high-efficiency Plug Fan centrifugal fans and units based on them
Country: · Model: PF, PF/EC, CJPF
PF is a Plug Fan centrifugal fan, that is, a free impeller without a spiral casing, with sizes from 925 to 2180 and motors of 0.37–18.5 kW. The blades are backward-curved and the drive is direct. The impeller works directly in the chamber of a ventilation unit, air conditioner or air handling unit.

Description
The air is distributed across the cross-section of the unit without a spiral scroll, so such a fan is built into a chamber rather than installed as a separate casing. The frame is galvanized steel, and the pressure measuring port makes it possible to regulate airflow and pressure automatically. The motors are AC IE3, three-phase 230/400 V up to 4 kW and 400/690 V above 4 kW, 50 Hz, and the air temperature is from −25 to +60 °C. All sizes except 1871 and 2180 can be installed vertically. The PF/EC version has an EC IE5 motor with built-in electronics, and its maximum airflow according to the datasheet is about 25 700 m³/h. PFA/EC is more compact and higher-output, also with an IE5 motor, and PF/ATEX is intended for zones 2G/2D. CJPF is a unit in an acoustic casing on an aluminum profile frame, with 25 mm replaceable covers, an inlet collector with diffusers, anti-vibration mounts and standard flanges at the inlet and outlet. The CJPF-1240 … CJPF-2180 range has a power of 0.75–4 kW and an airflow of up to 21 500 m³/h.
How to choose
PF is taken for building into a ready-made unit, and if a separate unit with flanges for ducts is needed, CJPF in a sound-insulated casing. When smooth airflow variation without an external converter is needed, PF/EC is chosen. For operation at speeds different from the nominal one, a PF with an IE3 motor needs a frequency converter. On request, two-speed motors, stainless steel and the PF/ATEX and CJPF/ATEX versions for explosive atmospheres are available.

FAQ
What is a Plug Fan and how does it differ from an ordinary centrifugal fan?
It is an impeller with backward-curved blades without a spiral casing, and it works directly in the chamber of the unit. For this reason PF is installed in ventilation units and air conditioners rather than in a duct.
What is the maximum air temperature for PF?
The air temperature is from −25 to +60 °C.
Can the airflow of PF be regulated automatically?
Yes, there is a pressure measuring port on the frame, and automatic control of airflow and pressure is built on it. For speeds different from the nominal one, a frequency converter is needed.
What is the airflow of the PF/EC and CJPF versions?
According to the datasheet PF/EC gives up to 25 700 m³/h, and the CJPF-1240 … CJPF-2180 range up to 21 500 m³/h.
Can PF be installed vertically?
Yes, the vertical version is available for all sizes except 1871 and 2180.
