For example, tapping into a system with another duct may create a path of lower resistance that diverts air from the original sources. Additionally, to further promote longer filter life, see that each pulse duration is set as short as possible, generally around 0. The best size and shape are dependent on many factors, but hoods usually incorporate tapered or conical designs improve capture velocity and reduce friction in the system. Now you are ready to size the main trunk line. Calculate the SP of all branches to determine which has the greatest Rockler Dust Collector Quality SP.
Nov 01,  · For years, purchasers have resorted to minimum efficiency reporting values (MERV) in selecting dust collector solutions. The MERV rating scale, however, was established for general HVAC ventilation by ASHRAE standard MERV ratings . Designing Your Dust Collection System. There are two phases to designing your dust collection system: The first phase is sizing your duct work for adequate volume and velocity of flow for the type of dust you will be creating; and the second phase is computing the static pressure (SP) Industrial Dust Vacuum Systems 10th of your system to determine the size and power of your dust collection - on: Yellow Pine St. NW, Minneapolis, , MN. we calculate the efficiency of the dust collector: C-c 1J =--X c % The calculated parameters 11 and E are the basic criteria for evaluation of the performance of dust collectors when carrying out attestation and comparison tests. Apart from these Industrial Dust Vacuum Systems Design parameters it is possible to determine experimentally.
