The FX 250 range are self-contained, high efficiency, envelope type units of compact design. They incorporate fan, motor and filter assemblies with mechanically operated shaking mechanisms

This second hand FX 250 is an extremely versatile fine dust filter, capable of handling numerous dust types over a wide range of applications. 



  • The FX 250 range are self-contained, high efficiency, envelope type units of compact design. They incorporate fan, motor and filter assemblies with mechanically operated shaking mechanisms and are designed to accept combinations of fan volume/cloth area to meet the varying applications in industry. 
  • Full width hinged access doors, with quick release fasteners, provide easy inspection or removal of fan, motor or filter.
  • This unit has been produced with the additional features of a pre-separation chamber to help separate light dust from the air-stream before they make contact with the filter bags.
  • The shaker control when activated will stop the fan motor and allow it to come to rest before starting up the shaker motor which will run for between 30 and 60 seconds dependent on the timer setting.
  • The FX filter performance enables the recirculation (in some circumstance) of filtered air back into the process area, promoting cost savings through energy efficiency by the return of treated air.

Technical specifications:

FX 250 

  • Capacity 2000cfm @ 7" swg // 3400m³/hr @178mm
  • Fan size 5.5kW / 7.5Hp

The above design duties are based on an 8:1 cloth to air ratio. Polyester needlefelt filter media is standard. Other filter medias are available.

How do Dust Extractors Work?

Dust collection systems work in a variety of different ways but all have general principles in common. They draw process dust and particulates from the air through a filter that first captures and separates the matter, and then discharges decontaminated air back into the workplace or environment.

Dust extractors are used in many different and varied industries and so different demands are made of them; however all have common components such as a blower (or fan), dust filter, filter cleaning system, dust container and dust removal system.

Five common types of dust collection equipment are fabric filter baghouses, inertial separators (like mechanical cyclones), cartridge collectors, wet scrubbers, and electrostatic precipitators.

Importance of Dust Extractors

Dust in the workplace can affect product quality and employee´s health. Having a dust-free environment is essential to the health and safety of the workforce. Not only does it affect the health of employees but the dust covers the equipment affecting production processes and quality of the products. 

Capturing the dust at the source prevents it from spreading, done by using a dust extractor system to facilitate the important housekeeping to avoid it from accumulating.

What are Shaker Dust Collectors?

Shaker Dust Collectors contain a number of woven bags, which are fixed onto rails and use their surface area to capture dust as it is drawn through the extraction unit by its fan.

Bags are periodically cleaned by rapidly shaking the bags through a shaker motor and linkage system which removes the filtered dust from the bags and into a collection bin.

These units are commonly used in foundries, steel mills, the mining industry, power plants, and smelting industries.
