High Speed Abort Gate EM-HSAG 8”-58”


EcoMAXX™ High Speed Abort Gates are engineered with Triple Security. Activation is achieved by over pressure without electric signal, activation by electronic spark panel and/or activation signaled by a rapid temperature rise in the clean air duct plenum. A NEW INDUSTRY STANDARD! DESIGNED SAFETY SMART EcoMAXX™ High Speed Abort Gates are engineered with TRIPLE SECURITY. Activation by over pressure & without electrical signal Activation by electronic spark detection signal Activation by rapid temperature increase in clean air duct plenum An EcoMAXX™ High Speed Abort Gate is a NFPA required safety device that is necessary when potentially hazardous filtered air is returned to a building or workspace. The EcoMAXX™ HSAG is designed for installation in bag house & dust collector return air systems to automatically vent harmful gases to atmosphere, should a fire and/or explosion occur. EcoMAXX™ High Speed Abort Gates are an integral component for dust collection systems & are recommended for use with EcoBOSS™ Energy Management Systems, EcoMAXX™ Explosion Isolation Valves, EcoMAXX™ Fire Break Shutters & EcoMAXX™

Spark Detection and Extinguishing Systems

EcoMAXX™ Spark Detection & Extinguishing Systems combined with an EcoMAXX™ FireBreak Shutter offer the ultimate protection against dust collector fire and explosion. The standard EcoMAXX™ Fire Control Panel is designed to operate up to (5) five individual duct zones that include the installation of additional detectors and FireBreak Shutter.


Explosion Vents
Model #EM-XV
A Solution to Avoid Personal Injury & Damage to Property


EcoMAXX™ Explosion Relief Vents are ATEX Certified and available in domed & pyramid styles. All panels are laser cut using AISI 316L stainless steel and include a zinc plated external flange with standard AERSTOP NIZ PTE gasket. Alternate PTFE and SILICONCELL gasket are available. An optional internal grill provides support for applications having negative pressures to -24” WG.


Standard EcoMAXX™ Explosion Vents are tested (see price for exceptions) to perform at a breaking pressure of 1.45 PSIG (0.1 bar), Kst Max = 900 bar m/sec, Kg Max = 550 bar m/sec and Pmax = 9 bar, Pred Max = 2.0 bar. Every manufactured lot goes through destructive testing to insure quality and ATEX Performance Specification.


EcoMAXX™ Explosion Relief Vents are a non-reusable safety device that is designed to relieve explosive pressure in a dust collector or vessel without fragmentation. An optional ATEX Certified Signal Sensor is available that will initiate shut down and/or deactivate additional devices, should an event occur.

The size and quantity for selection of explosion relief panels is specifically dependent on the volume of the vessel and the explosive (Kst) value of the material being collected. It is MOST IMPORTANT that choices be made in compliance with the current NFPA 68 Standard on Explosion Protection by Deflagration Venting as well as best industry practice.


EcoMAXX™ Explosion Relief Vents are available for special requirements. Boss Products will provide pricing for non-standard applications along with sizing recommendations.
