Pass Through Hatches

Cleanrooms Australia’s range of pass through hatches offers simple, sturdy efficiency at its best.

All our pass through hatches are constructed by Cleanrooms Australia in Australia for the Australian market, and designed to achieve the highest levels of strength, longevity and serviceability.

Designing and constructing our pass through hatches in Australia comes with the added benefit of a short manufacture and delivery time, and minimises the cost of restricted production.

Our pass through hatches are available in a wide range of models and, because they are manufactured locally, any size variation can be accommodated.

The units are competitively priced against international suppliers, and when heavy loads need to be accommodated, the hatches can be matched to our tote trolleys to help prevent OH&S injuries.

What is a pass through hatch?

Pass through hatches are used to move material into and out of a cleanroom facility.

They constructed from stainless less steel and are available in a number of standard sizes. Pass through hatches can be floor mounted for use with trolleys, or mounted on a wall or bench.

Our units are custom made to order. That means we can construct a pass through hatch to any size or design is without international shipping delays.

Why would I need a pass through hatch?

Human traffic is a leading cause of contamination in a cleanroom environment. Pass through hatches allow materials to be moved into and out of a cleanroom without the need for staff to enter or exit the facility.

This reduces the risk of human contamination and increases efficiency while retaining cross-contamination integrity.

What are the different types of pass through hatches?

Standard

All our Standard pass through hatches can be manufactured in steel or stainless steel, and come mechanically interlocked as standard. They are the most popular and cost effective model.

Bleedthrough

Our Bleedthrough hatches are connected to your house clear air supply (HVAC) and allow material inside the hatch to be continually washed by clean air to minimise the level of possible contaminates entering the clean zone.

Terminally (HEPA) filtered

The Terminally Filtered pass through hatch is specifically designed for use in environments where protection is important for operators as well as the product, as in cytotoxic rooms. It ensures the highest level of contamination control.

X20 radiation

These hatches are specifically designed and constructed to be used in x-ray or hot works areas. They are often used in conjunction with a room installation of an X20 standard.
