Nordfab can assist customers in designing a blast-gated system, taking into account flow dynamics that will be affected by blast gates. While blast gates can be used to effectively utilize an undersized filtering system, they can also destroy the flow if not properly placed. Contact Nordfab or your local dealer to request assistance.
