CALL: A.WIHARTA 081294124885 085778084789 087784022201   Info Produk PM 0.1 Principle Fiber filters utilize several mechanisms for aerosol collection such as inertial, gravitational setting, interception, and diffusion. Each collection efficiency depends on particle size and filtration velocity. Large particles are collected in a filter by inertial impaction at a high filtration velocity while small particles are removed from the air by Brownian diffusion. The Model 3180 controls its diffusion collection increasing filtration velocity, and collecting particles only by inertia. Applications Aerial Environmental Studies Health Impact Assessments Indoor Aerosol Classifications Vehicle Emission Studies Features Particle classification as small as 0.1 micron meter Five stages of PM: 10, 2.5, 1.0, 0.5, 0.1 and backup filter Large sample flow rate of 40 L/ min
