Technical construction
The MTL 801 1/3D uses an antistatic filter (5,000 cm², Ø 420 mm) made of M-class polyester that effectively retains dry and potentially combustible dust. A HEPA H14 filter with 11,000 cm² surface area is tested according to EN 1822-5 (MPPS method) with 99.995 % efficiency. The motor delivers 2,500 mm H₂O vacuum and 180 m³/h airflow. The filter housing and collection tank are made of AISI 304 stainless steel, while the motor head and frame are made of painted steel.
Safety and applications
