By installing Philadelphia Safety Device explosion relief doors, you eliminate the time and cost of membrane replacement forever. Because unlike single use metal vents, PSD gives you a real door. A door that maintains a positive seal until it opens under precise and predetermined pressure conditions. A door that once opened, remains open until you close it- with little force and no tools.
PSD explosion relief doors are available in a variety of standard sizes. The number and size of doors required is a function of the vent ratio for the particular application. Our technical staff can assist with the selection of the correct doors for your applications.
Our unique explosion relief doors are engineered to afford superior pressure relief protection for your captial equipment. The design incorporated a wide range of features including dual purpose design, easy installation, lightweight door panel, smooth rear face and dry bearings.
