Cleaver-Brooks stainless steel vents feature a male/female slip-type jointing system allowing the flexibility for various models to fit in one another eliminating the need for adapters making them easy to install. All vent systems are UL, cUL listed, laser welding and ideal or commercial, industrial, and institutional applications.
Chimney liners – single wall stack/liners
Boiler Exhaust – single wall, air insulation double wall stack, mineral fiber double-wall stack, ceramic fiber insulation double wall stack ranging from 1” to 4”.
Freestanding stacks – factory welded cylindrical freestanding stacks with single, inner, and outer structure options.
Special Gas Vents for Condensing Boilers – single wall stack/liner, air insulation double-wall stack, and mineral fiber double-wall stack from 1” to 2”.
Grease Ducts – Cleaver-Brooks stainless steel grease ducts feature a male/female slip-type jointing system allowing the flexibility for various models to fit in one another eliminating the need for adapters. Grease duct products are suitable for installations using exhaust system components for the removal of smoke and grease-laden vapors. Ideal for commercial, industrial and institutional applications ranging 2” to 4” in single wall, air insulation double-wall, and ceramic fiber double-wall types.
Selective Catalytic Reduction (SCR) – Cleaver-Brooks’ Selective Catalytic Reduction (SCR) system uses ammonia as a reducing agent, which is introduced into the flue gas stream. This mixture then comes in contact with a catalyst, selectively transforming the NOx into harmless nitrogen and water. With the addition of SCR, NOx emissions can be reduced down to 1 ppm. SCR works with firetube, industrial watertube, heat recovery, and retrofit boiler applications.
Models PS and IPS are modular, prefabricated piping systems which employ flanged joints designed for both quick assembly and pressure-sealing capabilities. They are usable for a wide variety of applications, including:
- Chimneys and stacks for boilers and other types of building heating equipment
- Chimneys for industrial ovens, furnaces, and processing equipment
- Exhaust piping for engines or turbine units
- Ducting in restaurants for compliance with Type 1 hood requirements
- Ducting for heated air and combustion products
- Ducting for light duty pollution control equipment
- Venting for engine exhaust and other shipboard systems
- Venting for offshore drilling rigs
Jeremias exhaust systems have a unique, leak-proof product that has the highest pressure rating for the UL approved flue products.
- UL Listed
- Easy installation due to perfect fitting plug-in system
- No welding on-site needed

LFSystems Laundry produces exhaust and combustion air products.
Laundry Exhaust System (LES) maintains a constant pressure in the laundry exhaust system. Designed with EC-Flow Technology™, the LES takes advantage of LFSystems. bi-directional pressure transducer and proprietary PID technology to rapidly respond to varying manifold pressures due to load changes in the laundry exhaust system. Utilizing the Truline™ DEF Dynamic Exhaust Fan and an L-series control, the system can receive a start signal through a current sensing relay or may run continuously. Learn more
Stairwell Pressurization System
Properly ventilate stairwells in the event of a fire. The Active Compensated Stairwell Pressurization System uses an LFSystems controller to maintain a constant positive pressure boundary in the stairwell, elevator or multi-zoned area by controlling a supply air fan and optional motorized relief damper.
