Room Pressurisation and Ventilation

Freudenberg Filtration Technologies Room Pressurisation Units can be used anywhere that dust ingress is a concern, including clean rooms, switch rooms, control rooms, laboratories, critical plant rooms, workshops and more. Freudenberg Filtration Technologies Room Pressurisation Units have been used on MCC rooms, marshalling stations, substations, control rooms, telephone exchanges, offices, storage rooms, to name a few.

The presence of dust and other contaminants is of such a significant concern and a common issue for businesses operating in mining areas. companies are eager to protect their critical electrical componentry from failure due to dust migration.

Due to the intrinsic nature of some industries and the location of some worksites, indoor room environments can be dusty.

It is becoming clearer that these environments can lead to equipment damage, arc flash accidents, safety hazards, health complications and poor performance (human and equipment).

Our range of Room Pressurisation units have been designed with simplicity and efficiency in mind.

Application

The applications are vast as they can be used in any room or vessel that requires a dust‐free, well‐ventilated environment.

Freudenberg Filtration Technologies Pressurisation Units apply positive pressure using filtered air, which creates a slighly positive pressure in a room and prevents unfiltered air from entering the space through doors, windows and other leakage gaps.

 

Exhaust and recirculated air filtration in ventilation system application areas.

  • Intake air filtration for gas turbines and compressors
  • Industrial processes (chemicals, pharmaceuticals, foods and beverages, optics, electronics, surface treatment, etc.)
  • In sophisticated air-conditioning applications (laboratories, libraries, museums, airports, office buildings, etc.)
  • As policing filters for quality control in dust removal applications

Model FK: Modular compact unit for small volumes

The Varivent units in the FK range are designed for small air volumes of up to 0.15 m3/s. Due to their compact design, they are suitable for applications where space is restricted and are ideally suited for ground floor applications. Varivent FK are externally wall- mounted and come with a modular fan and filter unit with air inlet screen and outlet louver. They are equipped with a centrifugal fan. The filter type can be selected according to atmospheric conditions and operational requirements. Standard material of construction is 3CR12 with Mild steel and 316L stainless Steel being optional.

Model F: Robust pressurising unit for reliable performance

The F-range Varivents provide air volume flows between 0.5 and 2.0 m3/s. It is fitted with an axial fan, that can be driven by motors of different voltages according to the customer’s requirements. They are designed for external wall mounting and ideally suited for ground floor application. F-Varivents are equipped with air inlet and outlet screen. The filter type can be selected according to atmospheric conditions and operational requirements. Standard material of construction is 3CR12 with Mild steel and 316L stainless Steel being optional

Model G the biggest standard model

The Varivent G-model is the biggest standard model with an air volume flow of up to 5.0 m3/s. It is equipped with an externally mounted robust fan and filter unit with inlet louver doors. It can be wall or foot mounted. The axial flow fan can be driven by motors of different voltages. The G-Varivent is available in mild steel with 3CR12 and 316L stainless steel being optional. The filter type can be selected according to atmospheric conditions and operational requirements.

PAT Varivent: For heavy duty applications

The PAT-Varivent range offers air volume flows between 0.15 and 1.5 m3/s. It is equipped with reverse-pulse self-cleaning cartridges that can handle high dust loads where concentrations are in the region of  >5 mg/m3. The unit is wall mounted and ideally suited for ground floor applications. PAT Varivents are ready-to-use. They only require pressurised air for the reverse-pulse and a suitable electrical connection.
