HEPA Filters are installed where the highest level of air filtration is required in applications such as clean rooms, operating theatres, research facilities, the electronics industries, nuclear and pharmaceutical industries.
The filtration medium is provided by microfine glass fibres formed into a paper-like surface, supplied in various grades depending upon filtration efficiency required. The filter paper is formed into a close pleated package to provide a large surface area.

Airclean have been manufacturing Deep Pleat style air filters for over 30 years. Deep Pleat HEPAs are now considered as the “Old Fashioned” style of HEPA filter in the industry, however there is still market demand for this product due to its unique capabilities.
Mini Pleat and Wedge HEPA Filters are the more modern style of HEPA filters and are available in all HEPA Filter Grades.
HEPA cassette filters are a complete disposable unit including a rear mounted spigot offering an economical alternative to a HEPA Terminal Housing.
HEPA filters are generally available on a 2-3 week lead time.
HEPA (Absolute) Filters are used in a wide range of applications, such as cleanrooms, and operating theatres.
Other HEPA Filter applications include research facilities, electronic and micro-electronic industries, nuclear and pharmaceutical industries and where a high level of air quality is required.
Cleanrooms tend to employ the narrower 146mm deep HEPA Filters and utilise a lower face velocity in accordance with the relevant Cleanroom Standard.
The Cassette (HEPA) filter offers an economical method of installing a HEPA Filter into a Cleanroom, offering an alternative to the HEPA Terminal Housing. The Cassette HEPA Filter can also be used to create a Laminar Flow Cabinet or a specific application with the minimum of engineering.
Applications include clean rooms, operating theatres, research facilities, the electronic and micro-electronic industries, nuclear and pharmaceutical industries and high speed turbines.
A Laminar Flow Cabinet offers a localised clean air solution which can operate up to Class 5 of ISO 14644-1:2015.
A Laminar Flow Cabinet is designed to protect the working area from contamination by particulates. The Laminar Flow Cabinet will also force internal contamination created by the process away from the working area.
Typical applications for Laminar Flow Cabinets include electronics and microbiological work such as Mycology (mushroom culture growing).
A Laminar Flow Cabinet offers a localised clean air solution which can operate up to Class 5 of ISO 14644-1999.
Typically this is for use in microbiological or electronics applications where clean air is required on and around a workbench, or in a small environment.
The fully painted cabinet incorporates a fan, HEPA Filter and Speed Controller which can then be combined with a holding solution, such as a free standing frame, or workbench to make the Laminar Flow Cabinet a practical solution.
The Air Handling Unit is a double skinned panel insulated unit with a plastic coated leatherette finish. This AHU houses a direct drive backward curved plug style EC fan and a Bag Pre Filter at grade M5 to EN779:2012. A control box is supplied either fitted or loose with the unit, with a fully adjustable speed controller using a 0-10V signal. This allows the user to adjust the flow rate of the volume of air to the HEPA Filter, and into the room to be pressurised.
Wedge HEPA Filters are used in a wide range of applications, such as cleanrooms, and operating theatres.
Other Wedge HEPA Filter applications include research facilities, electronic and micro-electronic industries, nuclear and pharmaceutical industries and where a high level of air quality is required.
Airclean Tractor Filters are replacement filters for those installed in Tractor Cabs, to control the levels of pesticide entering the cab during spraying etc.
This Low Level HEPA Extract Housing offers a solution where contaminated air must be extracted to atmosphere, and needs to be deemed safe for discharge.
This system has been adopted for use in Isolation Wards, testing laboratories, Pharmaceutical Manufacturing facilities, to ensure the safety of the discharge, and facilitate the diagonal airflow in a room i.e. ceiling supply to low level extract.
Its high-quality white finish allows for the unit to be in keeping with a medical environment and cleanable.
