ACME DUCTMASTER
™
SINGLE & TWIN DUCT
BLOWERS DM SERIES
FOR INDOOR USE ONLY
An all-purpose CABINET BLOWER with a compact optional FILTER
SECTION.
Widely used in conjunction with HEATING, COOLING and
VENTILATING systems.
(Shown with Optional Series F200A Filter Section)
Acme certifies that the DM Series Duct Blower shown hereon is licensed to bear the AMCA Seal. The ratings shown are based on tests
and procedures performed in accordance with AMCA Publication 211 and Publication 311 and comply wit h the requirements of the AMCA
Certified Ratings Program.
An economical, quiet and efficient solution for many air moving
requirements.
Available with 7”, 9”, 10”, 12”, 15” and 18” blower.
CONSTRUCTION FEATURES
• Blower is equipped with ball bearings which have an
operating temperature range of -65º to +250ºF.
• 9/16” mounting holes are provided in the top of
cabinet for support rods when unit is suspended
overhead.
• Hook bolt motor mounting allows 7” through 12”
models, single and twin units, to be used in the
up-flow, down-flow and horizontal flow discharge
positions.
• Heavy duty motor mounting brackets with motor
adjusting bolt and rubber bumper is supplied on 15”
and 18” models. Suitable for horizontal position
only.
• Access panels on both sides allow easy servicing to
blower and motor.
• Keywayed shafts are standard on both ends.
• Blower is rubber mounted for quiet operation.
• Twin Duct Blowers are tied together with steel
angle runners. Twin blowers are on a common
shaft and driven from either end.
OPTIONAL ACCESSORIES
• SERIES HC HOT WATER HEATING COILS
attach to blower inlet. Two row aluminum fin
copper tube with sloped drain pan for positive
condensate removal.
• SERIES CW CHILLED WATER COOLING
COILS attach to blower inlet. Four row
aluminum fin copper tube with sloped drain pan
for positive condensate removal.
• SERIES F200A FILTER SECTIONS are
insulated and supplied with 1” framed aluminum
mesh filter. All filter racks will accommodate
either 1” or 2” filter. Easily removed for servicing
through end access panel.

Performance shown is for installation Type B - Free inlet, Ducted outlet, without filter section. Power rating (BHP) does not include drive losses.
Performance ratings do not include the effects of appurtenances in the airstream. The sound ratings shown are loudness values in fan sones at 5 ft. (1.5m) in a
hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type B: free inlet fan sone levels. Sone values not documented in unlisted
areas. Twin unit data is derived from tests of single width fans.

Performance shown is for installation Type B - Free inlet, Ducted outlet, without filter section. Power rating (BHP) does not include drive losses.
Performance ratings do not include the effects of appurtenances in the airstream. The sound ratings shown are loudness values in fan sones at 5 ft. (1.5m) in a
hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type B: free inlet fan sone levels. Sone values not documented in unlisted
areas. Twin unit data is derived from tests of single width fans.

Performance shown is for installation Type B - Free inlet, Ducted outlet, without filter section. Power rating (BHP) does not include drive losses.
Performance ratings do not include the effects of appurtenances in the airstream. The sound ratings shown are loudness values in fan sones at 5 ft. (1.5m) in a
hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type B: free inlet fan sone levels.
Sone values not documented in unlisted areas. Twin unit data is derived from tests of single width fans. SI CONVERSION FACTOR
