Electric Motors PSC/AOM V230/1/50-60Hz permanently coupled capacitor. They have sealed for life sleeve bearings and a cast aluminium enclosure rated to IP40 with built in thermal overload protection. Insulation is to class ‘B’ 6-speeds are available (3-speed wired), of which three are usually wired to a fan speed switch.
Air Filters The synthetic media is cleanable efficiency is to class EU2-G2-M1.
