Material-Hatches for Cleanrooms

for the controlled infeed and outfeed of material between cleanrooms with different cleanliness classes.

As a system supplier, clean-tek manufactures active, passive and partially active material pass-throughs that are adapted to the requirements of the respective production process. Through our own production, we offer you as a system supplier a modular system with which we develop optimal cleanroom solutions. Individual special solutions are part of our standard. Due to the flexibility of our system components, we can guarantee almost unlimited variability.

All clean-tek material pass-throughs are equipped with electrical airlock locking. In addition to our standard dimensions, we also manufacture airlocks to fit your specific application.

Details of our various material hatches:

Actively ventilated material hatches:

  • Has its own fan
  • With integrated HEPA filter
  • Produces low-turbulence displacement flow with vertical airflow
  • Frees the products from airborne particles during the rinsing time
  • Meets cleanliness class A according to EC GMP guidelines, corresponding to cleanliness class 5 according to DIN EN ISO 14644-1
  • The doors are partially glazed
  • Designed for wall installation at parapet height or placed on the floor
  • Locking time is adjustable and indicated by an electric traffic light (red / green)
  • Easy and quick installation in various wall systems, flush with the surface on one side
  • Easy to clean and disinfect

The body consists of a torsion-free double-shell metal construction, while the outer and inner shells are made of brushed V2A stainless steel (1.4301). The integrated fan supplies the interior of the airlock with purified air via a HEPA filter. The return air is extracted via a return air duct at the bottom of the airlock and returned to the fan. The filter is changed inside the airlock.
