Extract Fan Testing

SERVICE OVERVIEW

We offer extract fan testing, either in conjunction with air tightness testing or as an independent service.

Many Building Control Bodies (BCB’s), including NHBC are now requesting commissioning data for extract fans to prove compliance with Building Regulations Approved Document ‘F’ and the Domestic Ventilation Compliance Guide.
This requires, in addition to commissioning details, air flow measurement tests to be executed with UKAS calibrated equipment.

As buildings become more airtight, as a result of legislation, more reliance is placed upon mechanical or passive ventilation to provide a healthy environment within dwellings. Correct ventilation ensures adequate fresh air and minimises heat losses.

We have the very latest automatic flow meter, with which to measure air flows. The method we use is referred to as the Unconditional Method. This gives a very accurate indication of air flows without the need for pressure drop compensation.

Extract fan testing

Installation and commissioning of extract fans is an important part of meeting these Building Regulation requirements and we are able to give practical guidance to customers on how to ensure their installations will best meet the required standards.

Ryedale Testing can give your fan installation the most accurate flow measurement currently available.
