Our Dedusting Tunnels remove loose particles of dust and particulate matter that accumulate on raw material containers like drums, cartons boxes, sacks or bags before sampling or dispensing. 

Such tunnels are designed to allow entry of objects from one end over a rolling conveyor with air nozzles blowing high-pressure air over the objects thereby removing any loose particles over the entering object. In addition to air nozzles, dedusting tunnels can feature rotating brushes in horizontal & vertical assembly to ensure greater protection of cleanroom or raw material contamination.

The tunnels are designed to perform consistently at low maintenance and high reliability. These tunnels can be designed to operate autonomously or respond on demand, depending upon the requirements.

The salient features of our exclusive array include the following:
    • High-velocity shower jets in excess of 20 m/s ensure efficient scrubbing action to remove particulate matter
    • Fully washable pre-filters remove around 85% of particulate matters, therefore reducing the load on HEPA filters and increasing their efficiency and life span.
    • Highly efficient HEPA filters with around 99.99% filtration efficiency for removing particles as small as 0.3 microns and larger.
    • Floor matting operated switch for sequential operation of the air shower.
    • Multidirectional air flow
    • Adjustable air nozzles
    • Permanently lubricated direct drive centrifugal motors and efficient blowers for maintaining appropriate face velocities of the air (6000 ft./min + 20 feet), while producing minimum vibrations and noise (less than 60 dB)
    • Indicator lights on both sides of the air shower for regulation of traffic within the cubicle
    • Emergency buttons on both sides of the air shower to prevent accidental lock-outs
    • Interlocked doors minimize any chances of contamination
    • Door interlocks operate on the magnetic system
    • Hinged motor/blower compartment access panels made of coated aluminium
    • Tamper proof junction box, placed on top
    • Emergency switch off button with audible alarm located within the shower cubicle
