Description

The Unimaster series dust collectors are self­contained, intermittent-duty dust collectors with
bag-style filters. Three standard configurations—
UMA-B, UMA-H, and UMA-D provide effective
cleaning in a variety of industrial settings.

Most popular is Model UMA-B and ships complete
with fan, easy-access filter assembly, multiple-inlet
hopper and dust bin with quick-release sealer gear.
Model UMA-H is a control unit with fan and filter
assembly only. The housing has an open bottom
and flanges to bolt directly to a dust container or
hopper. Model UMA-D includes a fan, easy-access
filter assembly, multi-inlet hopper and drum cover
assembly to fit a standard 55-gallon drum.

Standard sizes range from 43 to 753 sq ft of filter
area and features a UMA controller to control the
filter cleaning operation. Other options include
explosion relief vents, static grounding, weather
hoods and caster frames.

Purpose and Intended Use

The Unimaster dust collectors are used to separate
solid particulate from an airstream as part of a
manufacturing process. It is an ideal choice for
intermittent operations in plant processes. Several
small units can be installed at dust generation sites
throughout the plant resulting in total dust capture
and flexibility. Some typical installations include
blending/mixing, abrasive blasting, cleaning,
cutting, drilling, grinding, milling, packing,
polishing, sanding, and sawing.

Operation

Unimaster Dust Collector, Model UMA

During normal operation, dust-laden air enters the
unit through the dirty-air inlet. The velocity is
reduced and natural pre-separation, caused by the
effects of gravity, takes place and heavier
particulate falls directly into the collection bin or
hopper. Fine particles collect on the outside surface
of the filter bag and clean, filtered air passes to the
center of the bag and discharges through the clean­air outlet.

plenum /
silencer

fan

The Unimaster is an intermittent-duty collector,
which means that cleaning starts when the fan is
turned OFF and the appropriate fan run-down time
is complete. The solid-state timer automatically
starts the cleaning sequence 75-seconds after the
fan is turned OFF. This is the fan run-down time.
Power to controls must remain ON to operate the
cleaning mechanism. The vibration motor starts
and filter cleaning begins for a preset time of 30­seconds.
