POWERMATIC PM1900 Dust Collector
The POWERMATIC
PM1900 is designed with the
power to work with planers,
wide belt sanders and most
woodworking machines. Its
powerful dust-evacuating
suction, effective filtering,
multiple connection and
large collection capacity
make the POWERMATIC
PM1900 a capable central
dust collection system for the
whole shop. Plus, it packs
those capabilities into a
durable, space-saving
package that accommodates
virtually any shop size and
needs.

The POWERMATIC DC1900 is essentially the same machine but can be equipped
with the fabric style bags (left) or the canister kit. (right) The difference in height
between the bag and canister setups can be important in some shop environments with

machine without filter elements or catch bags allowing the buyer to “design” the system they
want. The fabric filter and catch bag sets as well as the pleated canister filters with five plastic
catch bags are sold as individual kits. This allows the purchaser to save money by getting the
POWERMATIC PM1900 with the filter style wanted without paying for and then discarding an
unused “standard” filter and bag sets.
Filtering Efficiency
The bag filter elements are 20” in diameter and 48” in length. Upright hooks are included to
support the bags when the POWERMATIC PM1900 is not running. Spring steel band clamps
secure the filter bags to the twin collector housings. The fabric collector bags use spring retaining
rings sewn into their upper edges that fit into a groove in the collector housings making
installation and removal tool free. Many manufacturers use an outside band for securing
collection bags that can be very difficult to work with, especially when done alone.
The bag type elements filters out 96% of 30 micron particles.
The canister filters are 20” in diameter and 29” long. The canisters mount directly to the collector
housings and seal with factory installed foam gaskets within the canister flanges. Four fingeroperated knobs lock each canister to the collector housings. Despite the canisters compact overall
size, its pleated filter element has six times the filtering surface area of the fabric bag type.
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

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 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 120degree 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
time. Eliminating those trips back and forth between a machine and dust collector can increase
safety in the shop as well.
Our remote control also has a timer function that allows
programming in a specific amount of run time between 1 and
99 minutes. When activated, the timer function allows the
POWERMATIC PM1900 to run a specific amount of time
before it shuts off automatically.

can save untold steps back and forth to
the DC1900. It also has a timer function
that allows programming in up to 99
minutes of run time before the DC1900
shuts off automatically.
The POWERMATIC PM1900 comes with a magnetic starter
(1Ph version only) that protects the motor from excessive
current variations. It also prevents the POWERMATIC
PM1900 from restarting unexpectedly should the power go
out, and then come back on. When the power is restored, the
On button (on the machine or the remote) must be pushed to restart the machine.
Fan System
We designed a super efficient air system for the POWERMATIC
PM1900, based on a specially designed 14”-diameter impeller and
housing. The heavy-duty impeller has been optimized to both move large
amounts of air and to maintain that volume consistently in a wide range
of usage situations.
The fan section develops 1,891 CFM (cubic feet per minute) of airflow
at 8” of water. Velocity, also at 8” of water is 5,393.7 FPM (feet per
minute). Static pressure is 12.15 inches of water.
To make the POWERMATIC PM1900 compatible with the widest range
of machines, it comes with a single 8”-diameter inlet port fitted with a
triple 4”-port adapter. Two of the 4” ports come with tethered, friction fit
covers that seal them when not in use.
The impeller is specifically
designed for maximum
efficiency and consistency
in the DC1900.
The inlet ports are mounted directly to
the blower housing, putting them low on
the POWERMATIC PM1900 and on an
even plane with the dust outlets on many
machines. This alignment keeps more of
the hose flat on the floor for safety and
eliminates much of the lifting loss higher
inlet ports experience to enhance
performance.
The smooth surfaces and curves of the sheet metal chute (left)
enhance airflow and efficiency. This triple 4”-outlet adapter (right)
slips onto an 8”-diameter port to provide the most versatility in your
shop.
To further enhance overall airflow we
replaced the common flex hose
connection between the fan and collector
housings with a curved, smooth-walled sheet metal chute. The ends of the chute have flange-type
connections with gaskets that help prevent even small leaks. This chute has a larger inside area
than a hose initially, and then tapers down slightly as it splits and then runs to the collector
housings. The smooth, flowing shape of the chutes interior surfaces move air efficiently and
contribute to the overall performance of the POWERMATIC PM1900.
The strength and rigid mounting of the sheet metal duct adds a considerable amount of stability
to the POWERMATIC PM1900 making it possible to eliminate two of the three legs normally
needed to support each collector housing. Eliminating two legs at each collector housing creates
substantially more unobstructed space that makes changing the collection bags much easier.
The collector housings are specially designed to create a cyclonic effect that helps separate
particles from the air to enhance filtering and venting. The swirl of air also helps distribute the
dust evenly in the catch bag.
Mobility
The POWERMATIC PM1900 is built on a heavy-duty base
that features full-swivel, smooth-rolling casters at each corner.
This base, along with the low center of gravity makes moving
the POWERMATIC PM1900 around the shop effortless and
safe. We also added a pair of handles to each collector housing
that make moving the POWERMATIC PM1900 easier.
