Do you cover Carlisle?
Yes. Carlisle is around 105 miles from our base in Lostock, Bolton. We plan visits to Cumbria into our regular service and filter change rounds, and travel for installations, refurbishments and LEV testing.
What types of sites do you work on in Carlisle?
Mainly food production, manufacturing, engineering and distribution across Carlisle, the M6 corridor and the rest of Cumbria, including Kendal, Penrith and west Cumbria.
How often should AHU filters be changed?
For optimal performance we recommend changing the air filters in your air handling unit at least every six months. Pre-filters on dusty sites often need changing every 3–6 months, while secondary bag filters usually last 6–12 months. The best guide is the pressure drop across each filter bank – we can fit gauges and offer condition-based monitoring so filters are changed when they need it, not before.
How often does an LEV system need testing?
COSHH regulation 9 requires a thorough examination and test of LEV at least once every 14 months. Some processes listed in Schedule 4 of COSHH need testing more often (as often as monthly), and records of each test must be kept for at least five years. We provide LEV testing and can put your system on a regular schedule so it never lapses.
Do you offer free site surveys?
Yes – FEL offer free site surveys and quotations for filter change contracts, remedial works and new system installations in Carlisle and across Cumbria.
