Negative Pressure Unit (1,200 m³/h)
Thermac’s new 1200 NPU is our smallest, most portable yet. Ideal for accessing airlock systems that are in confined spaces or where easy manoeuvrability is paramount.
The 1200 has a unique self calibrating digital airflow monitor, which has been neatly housed within the casing. Each NPU is constructed using a lightweight and robust ABS material making the units stronger, and easier to handle. They contain HEPA-14 filters tested to an efficiency of 99.995% (H14) and their overall performance provide the user with the confidence that these machines meet today’s stringent regulations. Each new machine comes with 12 months limited warranty, 6 months D.O.P. and electrical test certificates and has the back up of Thermac’s service support department.
Key features:
- Fitted with real time digital flow meter which is virtually maintenance free
- Self-calibrating system: 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 alleviates display drift and the need for periodic calibration
- Tilt & pull design for easy manoeuvring (especially up and down stairs)
- Small footprint
- Fitted with hour meter
- Clip free magnetic transit covers
- Complies with BS 8520.2.2009
