A pair of “hands” (left) within the canister flex the pleated

element to knock off excess buildup. The hands are operated by the external handle (right), which is generally turned through one revolution per month in most home woodshop circumstances.

The canisters filter 86% of 1 micron particles and 98% of 2 micron particles. To maintain that efficiency, a top-mounted handle operates a pair of “hands” within the canister. When turned the hands wipe across the interior filter pleats, flexing them to knock off excessive dust buildup but leaving the beneficial layer. Turning the top-mounted handle one full revolution per month (per canister) under normal conditions is all that is required. The oval POWERMATIC sticker on the canister exteriors can be easily peeled off the canisters wire mesh if one wants to remove any possible impact on performance though none has been recorded.

The difference in height between the fabric and canister filter elements can be an issue in shop spaces with low ceilings or overhead clearances. The POWERMATIC PM1900 has an overall height of just under 6 feet with the canisters installed compared to 92 ½when equipped with the fabric filter bags and their hangars.

Collector (catch) bag capacity for both the fabric and plastic bags is 10 cubic feet.

Power and Control

The POWERMATIC PM1900 is available in two configurations. First is with a 3HP, 1Ph 220V (only) TEFC (totally enclosed fan cooled) motor. We also offer a version with a 3HP motor running on 3Ph, 230/460V power, wired for 230V from the factory. POWERMATIC motors are rated using a continuous duty cycle rather than the “peak” or “max developed” claims so common in the industry. Very often new POWERMATIC users are pleasantly surprised by the amount of power our motors actually deliver when compared to other motors with similar power ratings in their shop.

The motor is secured to a common mount with the blower section, directly on the base platform. This creates a very low center of gravity that makes moving the POWERMATIC PM1900 safe and easy.

The 3 HP motor (1Ph version only) features a magnetic start switch that protects the motor itself, and you from unexpected power variations or outages.

Because woodworkers sometimes locate their dust collector in an out of the way portion of the shop or connected to a permanently installed hard tubing system, we added a full-function, infrared remote control (1Ph version only) that emits its invisible light-based signal in a 120- degree cone. That means the pocket-sized remote unit will turn the POWERMATIC PM1900 on and off from virtually anywhere (line of sight) in most shops, saving untold numbers of steps and
