Key features of the AM 400

Intelligent Operating System (iQ)
Advanced extraction monitoring and control system bringing multiple performance enhancements for higher efficiency of extraction, independent filter status monitoring and integral design features that combine to deliver a lower cost of ownership. It monitors the status of both the pre filter and combined (main) filter.

DeepPleat DUO pre-filter
This pre-filter comes in three main sizes and incorporates a massive drop-out chamber and large volume area within the base of the filter. Above the drop-out chamber but still within the housing there is a sealed 200mm deep pleat layer of F8 media giving an impressive surface area.

Automatic flow control (AFC) technology
Automatic flow control (AFC) allows the operator to preset the correct gasflow rates for the specific application, subsequently maintaining the gasflow. This generates lower noise levels and ensures further protection of the more expensive HEPA filters.

Reverse flow gas (RFG) technology
The RFG technology feature causes a fall in velocity and gas direction change. Larger particulate falls out of the gastream into the filter’s drop out chamber. With less particulate entering the filter media the filter life is significantly increased, enhancing filter capture performance and ensure longer life.

Patented technology
BOFA invests in innovation and our products and technology have a heritage of being tried, tested and trusted for over 30 years. As the market leader, we are proud of our product designs and technology and take great care in protecting this intellectual property and our integrity. Our product range includes aspects which are protected under patent copyright, design copyright, registered design and trade mark laws.

Low leakage
This unit is very low leakage:
<33ml/min @-10mBar.
Limits argon loss.
Limits oxygen ingress.

Electronics lift assist
This unit has electronic lift assist for ease of housing installation and disassembly.
Electronic actuator which lifts the housing by 100mm, using the buttons on the front panel.
Lifts up to seal against the tri-clamp fittings.

Removable filter housing
This unit has a removable and isolatable filter housing element. This keeps the contents securely under inert conditions during transport.
Double seal arrangement which results in:
<15ml/min @-10mBar loss.
Limits argon loss.
Limits oxygen ingress.
Ergonomic height.
Robust and ruggedised castors.
DeepPleat DUO, patent protected drop-out chamber.

ProTECT service plan
Our ProTECT LEV service plan and compliance certification has been designed to give you the peace of mind that your LEV (Local Exhaust Ventilation) systems are being expertly maintained throughout their working life and you are kept within government guidelines and regulations in the UK.
