FOEHN Push-Pull Pulse Jet Cartridge Dust Collector for Internal Factory Cleaning

To remove harmful mixtures, dusts, welding sprays, and clouds, a filtration and ventilation system is developed which entails two air pipes stationed at opposite walls of the facility at the height where the contaminated air forms.

From one gas pipe, the filter machine induces contaminated air and cleans it using a cartridge filter while it feeds the cleaned air back into the factory via the other gas pipe.

The contaminated air enters into the FOEHN Push-Pull via an air pipe or gas pipe into the dirty chamber. After that, the dust particles settle on a channeled cartridge while the clean air passes through the round cartridge and enters into the clean chamber. The cleaned air exists the filter with the help of a fan outside or goes back into the facility.

The specifications depend on the package elements. For each client, we create a project based on a detailed survey about the production site and the nature of the dust.
The dust collector can optionally be designed as unconventional, depending on the client's technical task.
Thanks to the technical advancements we’ve completed, we've managed to raise the carrying capacity and extended the filter's service life.

According to the technical task of the client, there may also be more modules.

We always accommodate the client and are willing to add all necessary functions, as well as other characteristics and parameters to the standard package elements.

A modification is a filter variation with a different quantity of modules. Adding modules entails a change in general performance, filtered air volume, size, and other specifications. FOEHN Push-Pull cartridge dust collector consists of one or multiple modules.

The recommended performance of a single module is no more than 18000 cfm and in order to increase the performance of the cartridge dust collector, it is required to install an additional module (see example in drawing below).

A collector can optionally be designed with non-typical size depending on the client’s technical task

Ensures air cleaning within the factory both at individual operation stations and throughout the factory, returning cleaned air back into the facility.

The Push-Pull system captures air, filters it, and returns it cleaned back into the factory.

The system configuration and package with different types of performance depends on the required air consumption and the particularities of the operation facility. Automatic control is implemented using a special panel.

In order to enhance air cleaning, install an additional special Coal type filter for gas elements after the cartridge filter is installed.

The performance of the filter, the length of the air ducts, the quantity of grids, and the consumption of air passing through them are calculated by Fakel's engineers based on the volume of the facility, the distance between the walls, the form of welding, the type and consumption of the welding electrodes, the brand of welded metals, and an array of other parameters.

Our dust collector design helps our clients money by not having to replace the bags as often. Installed in front of the filters is a dust chamber so that the dust settles right down into the hopper and this reduces the wear on the cartridges.


The damper plate helps achieve a more even distribution of gas flow along all the filter cartridges, which extends the filters’ service life and improves air cleaning, since the load is even and allows for operational costs savings.

In its standard package, FOEHN Push-Pull 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

Discharging organization methods for the client to choose from:

• The basic package features use of the manual method, which is done using a manual hatch which when opened manually and the dust unloads out of the dust aggregator into some volume or, when dust falls into a connected volume (box) without a hatch.The automated method: a flood gate or a double flap is used for unloading, often together with a worm transporter.
• The automated method uses a gate or double dump for discharge, often along with a worm transporter.

The main distinction is manual labor which must be exerted to unload the captured product. The automated method can be combined with a production line and, for instance, the product can be returned back onto a conveyor belt.
