250 micron, 316 Stainless Steel Mesh Insect Screen

Stainless steel insect screens (commonly referred to as “thrip screens”) are used in HVAC systems to provide a barrier against the migration of insects either into or out of a controlled space.

Typically, stainless steel insect screens are used as a biosecurity measure in AQIS regulated facilities or laboratory spaces requiring physical containment or barrier protection against insects (specifically those that will burrow through existing filter media such as mites and thrips).

Typical applications for stainless steel insect screens may include quarantine facilities, insectariums, research laboratories and hospitals.


These insect screens are manufactured as standard using 250 micron, 316 stainless steel mesh and a 316 stainless steel holding frame. Additional holding frame material options include zinc sheet, powder coated zinc sheet or 304 stainless steel.

A synthetic insect screen for greenhouses and non-classified areas is also available. This can be fitted into a frame to suit the individual client requirements.


Stainless steel insect screens are easily installed using holding frames that incorporate mounting studs. The insect screens can be fixed directly to the studs in the holding frame and secured with stainless steel wing nuts.  Alternatively, the insect screens can be mounted to the holding frame using a holding tab mechanism that utilises studs and clamps.
