PCJ Series
When selecting wall exhaust fan, it is important to consider the noise generated by the fan during operation. The PJC Series is a extra low noise range of wall fans with operating speed of the fan and motor at only 730 rpm and generating noise between 62 to 68 dB(A). At this noise level, it will not cause irritation to the workers even the entire workspace has no other machine noise.
The PJC Series also comes with a motorized insect prevention shutter as option. The shutter opens when the fan is turned on and closes tightly when the fan is shutdown.
JS Series
The JS Series is still a relatively low noise fan generating between 70 to 74 dB(A) noise level compared to other direct drive fans. This fan is belt and pulley driven such that the fan speed is kept at a low rpm of 480 to 520 rpm. All JS fans come complete with a gravity insect prevention shutter.
