Accessories
ECS manufactures a number of accessories to enhance, protect or extend the benefits of our equipment and solutions. Some notable accessories we offer include:
Prefilter or Grease Filter / Mist Eliminator (GFME)
These accessories protect expensive equipment or media by removing particulate and/or moisture before it can reach the odor control system. Some key benefits include:
- Protects fans and sensors from debris
- Extends media life in activated carbon systems
- Keeps biofilter media from plugging
- Comprised of high quality, fiber-reinforced plastic (FRP) material.
- Utilizes a segmented filter pad for easy removal and cleaning
The FRP, PVC, or SS housing of the prefilter is designed to ensure even air distribution across the filter pad. The goal is to maintain a consistent airflow, typically around 400 feet per minute (FPM), which helps achieve optimal filtration performance while minimizing the pressure drop.
Most filter pads are a combination of 2-inch-thick stainless-steel mesh followed by a 4-inch-thick pad constructed of polypropylene. The stainless pad removes grease or particulate and the polypropylene mesh removes free moisture. Both types of pads can be pressure-washed and reused.
Options available:
- Custom colors
- Quick-latches and hinged access doors
- Support legs or hanger clips
- Differential pressure gauges, switches, and transmitters to measure pressure drop across the filter pads
FRP Dampers
These are corrosion resistant airflow control dampers. Multiple resin systems are available to ensure the appropriate materials for construction. These dampers might be flanged or plain end, and they’re available in the following shapes:
- Round
- Oval
- Rectangular
Specifications:
- FRP, Stainless Steel (SS), Hastelloy or Titanium metallic parts
- Seal material — EPDM, Teflon, etc.
- Operators — hand quadrant operator, worm gear, electrically actuated, pneumatic
- Options — extended shafts, chain-wheel operators

- Excellent corrosion resistance
- High-quality construction
- Custom configurations/shapes
- Double O-ring shaft seals
- Uses include fan inlet boxes, intake points and fan outlets
Variable Inlet Vane Dampers
Radial vane dampers exploit the properties of fans by “pre-spinning” the air, affecting the rotation of the air to reduce the fan pressure without degrading speed. They allow for precise volume control where standard butterfly dampers do not.
Some advantages of variable inlet vane dampers include:
- Great for modulation and flow control
- Fast operating speeds
- Minimal outside space requirement
- Low maintenance cost
- Tight, vibration-free linkage
- Low torque operation through the entire range of open/close
- Excellent corrosion resistance
- High-quality composite construction
- Custom configurations and shapes
- Double O-ring shaft seals
Some applications of variable inlet vane dampers include:
- Precise volume control
- Increased fan efficiency
- Reduced intake turbulence
Back-Draft Dampers
These dampers provide immediate isolation of air stream or air space upon a loss of pressure.
Some key features and advantages include:
- Double O-ring shaft seals
- Optional blade seals for low-leak applications
- High-quality composite construction
- Custom configurations and shapes
- Immediate reaction
- An adjustable counterweight which allows for pressure control
Some useful applications for back-draft dampers include:
- Gooseneck intakes — These open to allow fresh air into a contained area where foul air is being drawn and they shut when air flow is neutralized
- Fan outlet/inlets — Inlets prevent backflow through the fan or ductwork system. They’re useful for isolating a fan and keeping it from spinning backwards without complicated automation.
- Exhaust stacks — These prevent backflow of fresh air into an odor control vessel when it is not operational.
In addition to in-house testing, ECS Dampers are tested in an independent AMCA certified laboratory to confirm performance.
PVC Ductwork
At ECS, we make PVC rolled or extruded ventilation ducts and fittings. We offer Type I, Grade I and Polyvinyl Chloride construction.
Some Benefits of PVC ductwork include:
- A cost-effective alternative to FRP or SS
- Quick, clean installations
- Minimal pressure drops
- Short lead times
FM Rated PVC Ductwork
FM-Approved FiresistTM ductwork negates the need for fire sprinklers.
FRP Ductwork
FRP ductwork is high-strength and filament wound ductwork comprised of corrosion resistant resin systems and can have flanged or plain-end fittings. Also available in custom shapes, colors and even a rating of ASTM E84 Class 1 flame spread designation.
Standards of design and production include:
- ASTM D3982
- ASTM D2992
- NBS PS 15-69
- ASTM D581
- ASTM D3567
- ASTM C582
- ASTM D2310
Quench Towers
Quench towers provide temperature reduction through evaporative cooling. They can condition polluted air streams that come from high-temperature processes, such as incinerators, boilers, kilns or oxidizers.
Sound Enclosures
Some key qualities of sound enclosures include:
- FRP construction
- Corrosion-resistant resin system
- ECS Sound-Adsorb lining for noise reduction
- Single-piece construction
- Ventilation louvers
FRP Biofilter Covers
ECS custom-designs FRP covers to meet project specific engineered loads.
Exhaust Stacks
These are free-standing or vessel-mounted stacks. ECS can custom-engineer exhaust stacks to extend to required elevations for stack tip/dispersion modeling heights.
Fume Hoods
Fume hoods serve a wide variety of industrial processes where toxic contaminants are present. They serve to capture fumes and route them into a ducting system where they can be removed from human and environmental contact. ECS designs fume hoods in accordance with American Conference of Governmental Industrial Hygienists (ACGIH) standards.
Fume hoods are chemical resistant and do not degrade as a result of gases, vapors or particulates that they capture. We can custom-build fume hoods in a wide assortment of configurations, including:
- Canopy style
- Side lateral
- Downdraft
- Upright
A wide range of materials are available for construction of fume hoods, including:
- Type I or Type II, Grade 1, Gray PVC
- CPVC
- FRP
- Polypropylene
- Dual Laminate
Key features of fume hoods include:
- Drip lips
- Low-point drains
- Internal reinforcement
- Adjustable slots
- Flexible outlet connections
- “Swing-type” hoods
- Pre-control mesh pads with wash-down spray headers
- Magnehelic pressure gauges
SweetVent (Passive vent filters)
A SweetVent is a simple passive device that attaches to the end of a vent stack. They’re available with slip-on or flanged connections.
They utilize positive pressure in the system to push the contaminated air up through the unit. The dry media absorbs odorous compounds, allowing clean air to pass through the end of the SweetVent into the atmosphere.
