UV Air Purifiers for Schools and Offices in Carlisle, Cumbria

UV Air Purifiers

For Schools & Workplaces in Cumbria

A UV air purifier for Covid and other airborne virus protection makes a lot of sense as we try to return to a new sense of normality. Our range of fixed and portable UV light disinfection solutions are a useful weapon in the fight against a resurgence of the pandemic.

In a typical Cumbrian winter they become especially useful when weather, temperature and rising energy prices make people less inclined to fully ventilate indoor spaces.

How The UV Light Air Purifiers Work

For your office or school

A small fan forces air to circulate through the unit. Air is pulled in at the bottom of the unit and pushed up through the interior of the UV disinfection lamp itself. Exposure to UV-C light damages the DNA of viruses, bacteria, mould and fungus particles rendering them inert and unable to reproduce or trigger infection. The disinfected/sterilised air is pushed out as clean air at the top.

UV-C light is harmful to people and animals, so the design of these units doesn't allow the light from the UV lamps to escape when people are around. Both the The Defender and Custodian can be used in rooms that are constantly occupied. In these models the light is permanently shielded and needs a hex key to open the unit for maintenance or cleaning. We can also order a third model, The Sentinel, which has a removable cover so it can be used to disinfect surfaces when people are out of the room.

We recommend these room air purifiers with UVC light for use in personal service settings such as beauty salons, health care practices, hotels, restaurants, local government offices, educational and care facilities. They can also be purchased for private use. The units can also have a HEPA filter fitted to further improve air quality by removing dust and other particles from the room.

These designs are capable of eliminating troublesome viruses and microbes from 110 to 160 m3 of air per hour, depending on the power rating chosen


This is a wall mounted ultraviolet light air purifier which comes in 72W & 144W versions. The Defender is designed be used safely in rooms that are occupied most of the time.

DEFENDER UV-C units are wall mounted and connected with a plug or wired directly into a fused switched spur socket.

Both the 72W and 144W versions have a lamp usage counter, adjustable fan speed and free-standing foot plate.

Efficiency and safety in use

The design of the luminaire interior ensures perfect air flow and the highest level of disinfection efficiency. The Defender luminaire is equipped with protection against opening. Removing the top cover requires a hex key.

Defender luminaires are available with a 3-metre power cord and without a cord (the so-called investment version).
