Powermatic PM1900 - Manual (Page 2)

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.
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 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 ½” when 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 3 HP motor (1Ph version only)
features a magnetic start switch that
protects the motor itself, and you from
unexpected power variations or outages.
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.
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
