HVAC FILTER MAINTENANCE
Filtration maintenance and management is critical for protecting the health of building occupants and protecting HVAC systems, associated components and the ducting.
How it works
Air Restore will create a database of all relevant HVAC plant and include the following variables:
- Asset no. or plant identification no.
- Location of plant
- Task description
- Service schedule
- Type of filtration, qty, media type and specifications
- Pressure drop readings across the filter bank
- Number of washers per filter for washable media re-order code
- Service notes and date of service
These database elements will be assessed to meet your requirements and will be used to create a tailored service schedule.
Common service schedules may detail actions like:
- Remove and clean pre-filters at the outside air intake
- Remove and clean pre-filters at the AHU
- Check the unit for unusual noise and vibration. Advise maintenance engineer
- Inspect secondary filters in AHU and advise maintenance engineer when replacement is required
- Record the pressure drop across the filters where there is installed provision for doing so
- Inspect coils and dampers, ensure they are clean and operational
- Inspect condensate drains and clean where necessary
Advise maintenance engineer of any corrosion or deteriorating paint - Inspect porous internal insulation for delamination or mould growth
- Advise the maintenance engineer if major works required or insulation is damp/wet
- Check for any air by-pass around filters and corroded filter housings
