Extractor Fan Testing Overview

Extractor Fan Testing Overview

Extractor Fan Testing Overview with APT Sound Testing

In adherence to the new regulations outlined in Part F of Building Regulations, it is now mandatory for standard intermittent extractor fans, commonly found in bathrooms and kitchens of new buildings, to undergo air flow rate measurement on-site. These results must be submitted to the building control body before completion and handover.

Our service facilitates extractor fan testing concurrently with air and sound testing, streamlining coordination efforts and offering significant cost efficiencies. Rest assured, our operations are conducted by a UKAS accredited company, ensuring quality and compliance.

Importance of Extractor Fan Testing

As modern buildings prioritize insulation and air tightness, it’s imperative that ventilation systems are appropriately installed, balanced, and commissioned to ensure optimal operation for occupants’ well-being. Approved Document F mandates that Mechanical Ventilation and Heat Recovery (MHVR) systems, along with intermittent extractor fans, have their flow rates verified, ensuring efficient operation. These test results are integral to building compliance and sign-off procedures.

In typical circumstances, we conduct Ventilation Flow Rate testing concurrently with on-site Air Pressure Testing, enabling streamlined compliance with both Part L and Part F regulations.

Best Practices Guide

a. Confirm ductwork complies with manufacturer specifications. b. Minimize duct bends to optimize airflow and minimize resistance. c. Use flexible ducts solely for connecting units to central diffusers to maintain acoustic performance. d. Employ recommended duct jointing collars and components for optimal duct performance. e. Seal all grilles and ductwork penetrating the building’s air barrier to ensure continuity. f. Ensure correct placement, securing, and adjustment of fans. g. Verify internal doors have 10mm undercuts as per regulations. h. Electrician should set fan speed according to manufacturer data. i. Secure air handling units to stable building elements using recommended fixing brackets. j. Install units in accessible positions for maintenance.
