1. The illuminated GREEN Light on the front of the Denford Advantage Extraction Unit, just means that both of the filters are not blocked and air is flowing freely through them. It monitors the pressure difference across both the filters.

2. If the RED Light comes ON then take either the 2 Stage Pre-filter or the Combined HEPA & Chemical Gas Filter out of the filter unit and switch it back on again. If the RED Light stays ON then the filter you left in the filter unit has expired, if the RED Light goes back to GREEN then the filter you have taken out has expired.

3. If the smell of the exhaust starts to get more and more pungent, even if the GREEN Light is still illuminated, then the Combined HEPA & Chemical Gas filter needs replacing

Hi
We have a situation where all the lights on our Denford Advantage extractor are flashing, the compressor is running, but there is no airflow through the extractor. The 2A fuse marked "PUMP" had blown, and blew again, noisily, when replaced.
I am getting no answer when phoning Denford.
Can you advise a course of action? Are there likely faults that are user sortable?

Hi,

Can you try calling Denford Service again?

Denford finish early on a Friday so that may be why you received no reply.

It sounds like the extraction pump could have failed.
