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.
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.
The infrared remote (1Ph version only)
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.
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 impeller is specifically
designed for maximum
efficiency and consistency
in the DC1900.
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 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
