Thermac’s new range of M-Series negative pressure units has been developed with the end user in mind and comes packed with new features and benefits to assist contractors while on-site. These include the unique self-calibrating, backlit digital airflow monitor, which has been neatly housed within the casing. 

This Variable Speed Unit has 3 speed settings (1300, 1800 and 2300cmh) which can be adjusted with the easy to use speed controller. This gives the end user the flexibility of having one unit which can fit into a number of different sized projects. 

Each NPU is constructed using a lightweight and robust ABS material making the units stronger, and easier to handle. They contain HEPA filters tested to an efficiency of 99.995% (H14) and their overall performance provide the user the confidence that these machines meet today’s stringent regulations. 

Each new machine comes with 12 months limited warranty and 6 months D.O.P. and electrical test certificates and has the back up of Thermac’s service support department. 

These units come complete with a Spigot Plate and Roving pre-filter box. 

Key features

  • Fitted with real time digital flow meter which is virtually maintenance free: the device is self-calibrating, when the unit is first switched on the display will auto zero, and as the unit is running continuously the display will auto zero every ten minutes. This is a unique feature as it elevates display drift and the need for periodic calibration.
  • Fitted with hour meter
  • Complete with Roving Pre-Filter Box for use when localised extraction is required
  • Clip free magnetic transit covers
  • Recessed handles
  • Complies with BS 8520.2.2009
