Pre-Filter for PAP 420

Portable Air Purifier 420
Recent events have made indoor air quality (IAQ) one of the most trending topics, highlighting the connection between indoor air quality and the well-being of the occupants of buildings.
We spend more time inside buildings than outside, with jobs and lifestyles that force us to spend more than 80% of our time indoors. Exposure in these environments to air contaminants−from dust to spores, bacteria or viruses, as well as the chemical compounds released by paint, claddings and furniture−has a direct impact on our immune systems and can cause anything from mild discomfort in our respiratory systems (for example, irritation and dryness) to much more serious health problems such as allergies, especially when the exposure to the contaminants is prolonged.

HEPA Filter for PAP 420

Fan Coil Unit - UVGI 2L
KEY FEATURES
High efficiency technology
Kill rate up to 99% effective
Can be retro-fitted to an existing fan coil
The Fan Coil UVGI 2L uses UV-C technology to irradiate virus and bacteria. The unit can be located in line with a new or existing fan coil unit as part of the room air distribution.
Each individual unit sits directly in the air stream and features 2 high output UV-C lamps.
UVGI inactivates micro-organisms by attacking their DNA, permanently destroying and altering the molecular structure, leaving them unable to replicate or grow.

Air Purifier and Irradiation Unit - Dual Tech
KEY FEATURES
Portable Dual Technology
Electrostatic Filtration - UVGI Irradiation
Highly efficient
ESP TECHNOLOGY
Electrostatic filtration is a method of removing tiny particles from the air, the system works by applying a static charge of around 8000v to particles in the airstream. These particles are then attracted to collector plates which have the opposite electrical potential resulting in them being stripped from the air. Filtration capacity is at a very high efficiency (up to 99%) even with sub-micron sized contaminants such as virus and bacteria.
The filter components used are metal and can be cleaned so there is no filter replacement necessary. A further advantage is that using static force to filter the contaminants provides a very low resistance to the airstream which enables better overall performance.

High Performance 75% Grease Efficiency Baffle Filter (Type 2)
For use in commercial kitchens and ventilation to extract grease laden air and act as a fire barrier. LONGAR® Type 2 HE75 is a positive flame barrier having been tested to European DIN Standard 18869-5 & American 1046 & ASTM2519.
The LONGAR® TYPE 2 HE75 is developed for customers who wish to extract more grease from the air stream, following prolonged R&D we have designed a baffle filter with a micro screen on the exit to increase grease extraction.
The result of this is a retrofit baffle filter that removes 75% of the grease at 8 microns. Tested to ASTM2519 this product significantly reduces duct cleaning, saving customers expenditure on ongoing cleaning costs. Conventional baffle filters extract grease in the region of 20 to 35% efficiency at 8 microns depending on the product design, the HE75 offers over twice the extraction rate.
