Circulaire® Mobile Recirculating Filtration Arm

The Mobile Fume Filtration Arm provides an exceptional level of point of use operator protection.

The arm easily rotates to almost 360° and all pivots and joints are deliberately located outside the airstream, this prevents contamination or clogging of the mechanical parts and ensures optimal inflow and reduced pressure drop – this in turn ensures low noise and high – performance operation.


Immediately add Recirculating Fume Extraction capacity to any laboratory or location.


Guaranteed operator protection provided through high performance filtration, specified to your requirements.

MonSci-Icons_360 Vision

The standard 2m radius arm offers an infinite range of extraction locations to suit your application.

MonSci-Icons-Recirc Tech

Sustainable Recirculating Technology consumes minimal energy and delivers optimal performance.

The Circulaire® PFB250 Mobile Recirculating Filtration Arm is simple to operate and easy to manoeuvre, providing quantifiable and fully testable protection. The inflow is 250m³/hour to give more than sufficient flow to offer point of use protection for all laboratory source fumes, vapours and light particulate protection.

The main filters consist of activated carbon that will be specifically matched to your application and are monitored with a hydrocarbon detection system to assist in the replacement of carbon filters. The status of the airflow into the cabinet is constantly displayed on the control panel and is monitored and controlled electronically by the microprocessor to ensure the optimal airflow is achieved at all times.
