Air Tightness Testing Equipment

Stroma Technology supplies calibrated test fans and equipment for carrying out air-leakage and room integrity testing. You can buy or hire any of the products in our Retrotec range, which includes calibrated fans, blower door fans, smoke pencils and manometers.

Since we use the equipment for our own testing operations, we are also ideally placed to provide after-sales support.

In addition, we offer BINDT training and calibration services.
