Baghouse Dust Collector with Compressed Air Pulse Cleaning
Bag type filter elements
cleaned with high pressure air pulses controlled by an automatic
efficiency venturi nozzles for efficient cleaning of the bags
Dirty air inlet plenum
integrated to the dust collector
Designed for heavy dust
loads to 100 grams/cubic foot of concentration
Air volumes from 1000 to
- A proven concept,
MAXITUBE dust collectors can filter a wide
variety of dusts in concentrations to 100 grams/cu. foot. A
separation plate protects the bags from the abrasive properties of
dusty air and distributes this air evenly at a slower velocity into
the bottom of the dust collector.
- A solid construction using
welded steel sheets of 10 and 12 ga, capable of resisting to 20 in H2O
- A quality finish made
possible by a paint application procedure in 3 steps. Step 1
consists in a thorough preparation of the metal by the application
of a phosphatized coating, after drying a base coat is applied
following with an industrial light gray polyurethane finish capable
of resisting tarnishing and rusting.
- Complete cleaning of the
filters due to the very strong sonic shock wave produced by the
ejection of a measured volume of compressed air from the MPH3
supersonic nozzles, strategically placed on the compressed air
- Excellent filtration
efficiency by the use of needlefelt polyester tissues, of superior
quality. MAXITUBE is available with
tissues such as polyester, acrylic, polypropylene and Nomex. All of
these tissues can have different finishes to solve specific dust
problems, these finishes are singed, glazed, PTFE, silicone and
- Designed for interior
access to the filters using a walk way. Some larger models (160 to
300) can be delivered with plenums for top bag removal.
dust collectors are compatible to all the different accessories that
could be required for a complete and safe industrial application.

- Saw mill
- Molding industry
- Cabinet makers
- Furniture makers
- Paint pigments
- Stone cutting
- Flour mills
- Carbon black
- Paper dust
During operation, dusty air
enters the dust collector from the side, the dust particles carried in
the air collide with the deflector plate. The air velocity is
substantially reduced causing a downflow air motion that separates the
heavier dust from the air while eliminating all abrasion to the
nearest bags. As the air is filtered, the dust residues form a dust
coat on the bags.
At regular intervals, a
compressed air pulse is injected to all the bags in a row from the
compressed air pipe, the resulting shock wave provokes the rapid
expansion of the bag, breaking the formed dust cake that falls in
lumps into the hopper.
The dust collector housing and
the hopper are built from 10 and 12 ga sheet steel with reinforcements
capable of withstanding 20 in. H20 pressure differential.
The ¼” tube sheet is reinforced and continuously welded to insure air
tightness without distortion. A steel deflector plate is welded in
place to protect the bags from the high velocity dust. A removable
walkway is installed on all models to 64a. The walkway is fixed on
larger models. The hopper is designed with a 608
angle to facilitate the flow of dust and is finished with a flange. A
solid square tube structure with bracings forms a solid support
Pulse cleaning is
achieved by an electronic sequencer, with timer adjustment
capabilities of the pulse frequency and duration. This control can be
used with a photohelic type control, the pulse sequence will begin
only when the high-pressure limit setting is reached, and will stop
when the low-pressure limit is attained.
The air to cloth ratio
is the most critical variable that can influence the cost of a dust
collector, and it’s efficiency. The higher the A/C ratio, the less
expensive the dust collector will be. Maxitube dust collectors
equipped with MPH3 high volume nozzles insure that a strong air bubble
will travel evenly within each bag from top to bottom throughout the
pulsed row. This great benefit makes Maxitube a better collector.
efficiencies are reached by the meticulous choice of the filter
fabrics, and the air to cloth ratio (see filter fabric table).
Maxitube offers a selection of the filtration fabrics the most apt at
filtering specific dusts.
