FÅ«z-Vent is designed to be used many times over or until it ruptures. It was designed to be safe, easy to use and cost effective. This innovative fusible vent pays for itself after only a few turnarounds of tank contents or cleaning. When it becomes necessary to clean or fill the tank just unscrew the black HDPE fusible vent, wash it and put it back into tank. The FÅ«z-Vent product replaces the expensive type of fusibles that get pried off, bent, torn, cross threaded, lost or thrown away and then need replacement with each filling or cleaning. The FÅ«z-Vent cuts the waste and is approximately 1/10th of the cost of the conventional re-useable design of solder-filled stainless steel products.
All Intermediate Bulk Containers are required to have a Fusible Vent to meet DOT/UN regulations.
The Department of Transportation regulations state in section DOT CFR 178.705 (2)(i) states that "IBCs must be capable of releasing a sufficient amount of vapor in the event of fire engulfment to ensure that no rupture of the body will occur due to pressure build-up. This can be achieved by spring-loaded or non-reclosing pressure relief devices or by other means of construction."
The unique patented design of the FÅ«z-Vent safety vent plug by American Machining Inc. meets and exceeds DOT/UN and offers many advantages and benefits starting with:
SAFETY - a patented two port venting is placed well above the threads thus allowing safe tank venting with any pressure build up with only a quarter turn. Venting always occurs away from operator and prevents champagne cork like popping.
FÅ«z-Vent has an engineered HDPE center ring is designed to soften and rupture without exceeding the design pressure of the tank and per DOT/UN specifications. As another safety added value the FÅ«z-Vent disc will rupture long before the tank will rupture. FÅ«z-Vent withstands exposure to UV light, most solvents and chemicals. FÅ«z-Vent is certified to meet and exceed DOT/UN standards. An EPDM gasket is included with the product.
The FÅ«z-Vent system includes, as an option, a stainless steel 3” NPS flange piece that can be positioned as needed and welded in place.
The optional FÅ«z-Vent flange is a precision-machined stainless steel smooth surface and clean flange that resists chemical attack and withstands the rigors of use. The SS fitting offers a flush fit on the inside of the tank to avoid trapping of product or material. Using the stainless steel threaded flange and HDPE fusible vent eliminates contact galling that can occur on expensive threaded pieces when screwing stainless steel into stainless steel.
