Dust Collector Description

The Blizzard bag filter NEW classic baghouses have earned themselves a reputation as reliable and thrifty dust collectors for solving any types of tasks related to cleaning air and gas of contamination. They are equipped with compressed air (regeneration) cleaning. The distinguishing features of these kinds of filters is the modular design which upon adding the modules allows for the device’s performance to increase.
Reduced bag length
If flat and round bags are to be compared, when flat bags are used, the length of the bag shortens under the conditions of the same filtration area.
Even regeneration
Impulse regeneration of flat, short bags is distinguished by the softer, even impact of the impulse on the entire area of the fabric.

Flat Bags: Compactness and Convenience.
A Ruffled Damper Plate is a Reduction on the Wear on Bags

Money saved on bag replacement
The dust settles directly into the hopper and reduces the wear on the bags.
Even gas flow distribution
This increases the service life of the filters and air cleaning improves, since the load on the bags is even and allows for operation savings.

Modular Design: Our Main Field of Expertise

Increase performance by adding an additional filtration module.
Bolt mounted SKD assembly is performed based on instructions, such as in furniture assembly. Without any welding or complex modulations.
Due to the modular design, delivering the filter requires no special transportation and takes less time.
Rapid performance modernization
Quick and easy installation
Quick, straightforward transportation

How It Works

How does a Blizzard Bag Filter NEW work
Contaminated air enters into the Blizzard bag filter NEW via an air pipe (or gas pipe) into the dirty chamber. After that, the dust particles settle on the bags while the cleaned air passes through the flat bags and enters into the clean chamber. The cleaned air exits out the filter and goes outside with the help of a fan or goes back into the facility.


The performance specification depends on the package elements. We create each project customized for the client bases on a detailed questionnaire on their industrial site and the nature of the dust.

A baghouse can be implemented in nontypical form depending on the client’s technical task.

Modifications, Size, and Drawings

A modification is a variation of a filter with a different number of modules. Adding modules entails a change in general performance, filtered air volume, size, and other specifications.

The Blizzard bag filter New consists of one or multiple modules.

The recommended performance rate of a single module is no more than 10600 cfm and it is recommended to install additional modules to boost the performance of a baghouse.

A filter can be completed with nontypical size, depending on the client’s technical task.

Baghouse Design and Diagram

Gas movement scheme inside and out of the filter
  1. Contaminated air enters via the dirty air camera via the gas entry flange and it hits the damper plate. When it hits, the gas gets scattered to the sides and the highly charged and heave particles are knocked off of the damper plate and they fall right down into the hopper.
  2. Then the gas continues on into the dirty chamber where the filter bags are. Since the damper plate has grooves, all of the bags in the operation process are properly loaded and the wear on the bags distributes evenly. That raises the level of air cleaning, the dust concentration that the filter can work with, and extends the service life of the filter elements.
  3. Air containing fine dust passes along the bags and the dust settles onto the outside of the bag while the clean air exits to the outside.
  4. After that, the air passes into the clean air chamber and is extracted out of the filter.
On the side of the filter are hatches that are used to remove the filter bags which is necessary to replace, diagnose, and repair them. Furthermore, an additional diagnostic hatch is located at the back of the filter.

Flat Filter Bags

Flat filter bags are the basic element of filtration. The bag consist of non-woven material imposed on top of a metal frame.
The bags can be manufactured out of the following materials:
  • Polyester;
  • Meta-Aramid;
  • PPS;
  • Material with an anti-static effect.
Advantages of flat bags:
  • The flat, short bag impulse regeneration process differs with the impulse's softer, more even influence on the entire area of the fabric.
  • If flat bags are to be compared to round bags, when flat bags are used, the length of the bag is reduced under the conditions of an identical filtration area.
  • The use of flat filter bags allows for the filtration area to be increased without increasing the filter device size.

Contaminated Air Entry: the Damper Plate

Our filter design saves our clients money by their not having to replace the bags. Installed in front of the bags is a grooved rust chamber to get the dust to settle directly down into the hopper and reduce the wear on the bags.

The grooves help for a more even distribution of gas flow along all the filter elements. This increases the filter’s service life and improves air cleaning, since the load on the bags is even and helps save on operation costs.

The Dust Hopper and Unloading It

In the standard package, Blizzard has a conical accumulator hopper for dust and a round gate with a manual gear for opening and closing or a box on wheels.

Additional hopper package elements
  • A vibrator or a vibration device to prevent dust from sticking to the walls of the hopper.
  • Level transmitter.
  • Hoppers and supports according to the demands of your production site. For instance, for our client, we tailored the hopper for big bag unloading at a wood processing enterprise.
  • The hopper is under the bag with a worm for uninterrupted unloading of dust from the hopper with a gate. Then the filter won't have to be stopped to unload the accumulated dust.
  • There is a hopper device for every module and one big one can also optionally be designed to which all modules will unload into.

Unloading the Captured Product

Methods for the client to choose from for organizing unloading

  • The basic package involves the use of a manual method. A manual flow gate is used, and after it is manually opened, dust unloads out of a dust reservoir into a container or, other times, the container (box) the dust falls into can be connected to the filter without a flow gate.
  • The automated method: a flood gate or a double flap is used for unloading, often together with a worm transporter.
The main difference arises when it comes to manual labor needing to be exerted to unload the captured product. The automated method can be tied into a production chain and, for instance, the product can be returned back onto a conveyor belt.

Managing the Baghouse

Smart control automation guarantees uninterrupted operation

Control of the filter is performed using a controller or a remote-control device. This system operates in a closed cycle, but it can be reconfigured depending on the client's needs.
We propose packaging the filter along with a system entailing completely automatic control, analysis, and fire extinguishing. A time controller is installed in the standard package and a Siemens controller can also be part of the package, depending on your needs.

Pneumatic Cleaning System

Periodically filtered bags get covered with dirt, which increases the filter’s resistance. In order for the system to work in an uninterrupted fashion without any pressure differentials, the bags need to be cleaned. Cleaning is done in the following way:
  1. On top, there are air pipes in the clean air chamber which start from the air system's diaphragm valves. These valves are installed for the receivers where the compressed air is kept, which is used for pulse jet.
  2. The air is submitted from the compressor to these receivers. Periodically, the valve begins operation and the air is submitted to the air pipe via the valve and then out of the air pipe with the help of the nozzles and is distributed inside the filter bag.
  3. The filtered bag is shaken and aired out while the dust falls down into the hopper accumulator from the filter bag.
  4. The dust can be extracted from the hopper accumulator in three different ways, depending on the technical task envisaged: the manual dust latch, a mechanical “double flap”, and an automatic “flood hatch”. The standard version has a manual dust latch included.

Impulsive Draft System Package:

Compressed air receiver package
It is the receiver that accumulates air for the pulse jet. If there isn't enough air, the degree of cleaning will fall, the wear on the filters will increase, and the filter’s performance will fall, since the aerodynamic pressure of the filter will increase. The receiver has a flanged socket for connecting to the compressor or the general factory compressed air pathway, as well as a moisture drain valve. If “Blizzard” isn't installed in a heated facility, we recommend installing an oil and water separation, thermal, and air heating system.

Air pipe system
These are either metallic or plastic. Everything depends on the gas and temperature that the Blizzard Bag Filter NEW filter is cleaning. Nozzles are installed on the air pipes for more efficient cleaning of the filter element.
Air valves
All our valves are certified. Our valves are specialized for filter equipment air cleaning systems.

Controlling the regeneration system is implemented with the help of a special controller that configures the impulse quantity and the frequency of them.

Differential manometer (by order)
Then bag cleaning can not only originate based on time but also in terms of the degree of the bags’ “contamination”. When the bags fall, the pressure in the filter changes and the manometer submits a signal to implement the draft. The differential manometer will also show an accident if one or more of the bags is ruined.
