• Powerful 3-speed air filter system for workshops up to 300m³ • Collects wood dust "hanging" in the air, filters 98% of particles 5µm and 86% 1µm • Remote control handset for speed and time periodsWith a powerful 150W motor, the AP25AFS Air Filter is intended for workshops of 300m³ or less. The air passes through the electrostatic pre-filter into the main pleated filter, filtering 98% of all particles 5 microns in size and 86% of all particles 1 micron in size. It comes with a remote control unit offering three settings for the motor speed and three different time settings of 1, 2 or 4 hours. This allows the unit to run after work has finished to clear the air ready for the next day. The machine runs reasonably quietly with noise levels of speed 1: 62 dB. speed 2: 66 dB. and speed 3: 68 dB. Supplied with electrostatic pre-filter, main filter and four mounting eyes. An optional charcoal filter is available, which will neutralise odours and harmful organic fumes or particles including pollen. The optional ceiling mounting kit consists of four lengths of flexible stainless steel wire with screw eyes and bolt up crimps allowing the machine to be hung out of the way. NB: The AP25AFS now comes with an Active Flow Sensor, which detects when the filter becomes blocked. When the filter is blocked an alarm will sound and the top row of lights on the control panel will start flashing. Once the filters are cleaned or replaced you will need to reset the system by holding in the 'on speed' button for around 10 seconds, then release. *This air filter is suitable for removing dry airborne wood dust particles and should always be used in conjunction with a dust extractor.
