Description
The Retrotec FN501 B8 Range Tray is designed for use with Retrotec 4000, 5000 and 6000 series fans. This part allows the equipment to be correctly configured for certain flow or pressure ranges ("Range B8"), ensuring that the fan operates within the appropriate parameters for "blower-door" tightness testing.
By installing the B8 plate, the technician improves test accuracy, facilitates fan calibration and reinforces the reliability of the equipment on site or audited. It is an essential accessory for airtightness consultants, energy auditing companies and sustainable building professionals who require repeatable and documented results.
