Table of Contents Model Application Pages Grease Hoods Type I Type I kitchen hoods are used over cooking equipment producing grease-laden effluent. 6-13 Type II kitchen hoods are designed to capture heat and/or condensate from non-grease producing appliances such as ovens and dishwashers. 14-18 Accurex offers industry-leading grease extraction filters to match your restaurant needs.
Decision Guide... 2 Easy Steps... 1. Will you be exhausting grease-laden air or non-grease-laden air? • Type I Hoods: Used if you are exhausting grease-laden air. • Type II Hoods: Used if you are exhausting non-grease-laden air (heat/condensate).
What style hood do I need? 2. Type I Hoods: What style of hood do I need? Is your cooking equipment against a wall? • Wall canopy hoods: Most common when the cooking battery is against a wall. Wall Canopy Hood • Proximity (Backshelf) hoods: Used when you have a low ceiling and/or it is to be placed over griddles and fryers, typically used in quick service restaurants.

Grease Hoods - Type I Model Comparison Wall Canopy Hoods. Grease Grabber™ H2O System Benefits Typical grease hoods, though low-cost up front, carry many overlooked and expensive maintenance issues that can lead to high costs over their lifespan. Capturing the grease generated by cooking processes is a challenge and the clean-up of grease is both costly and time consuming.
Grease Hoods – Type I Model Comparison Single-Island and Proximity Hoods. Proximity (Backshelf) Hoods Accurex proximity hoods have an industry-leading five dimensions of adjustment which make them the perfect solution for low ceilings and light and medium duty cooking applications. The Accurex proximity hood sits close to the cooking equipment allowing for lower exhaust rates and smaller hoods.

Filtration Options Accurex filters are UL 1046 Listed.
Filtration Options Quick Select Guide Accurex is the industry leader in grease filtration as verified by testing to ASTM F2519-2005 standards. This is crucial to the restaurant owner/operator because the grease generated by restaurant kitchens pose many problems; frequent duct cleaning, rooftop grease problems and compliance with tougher air emissions standards.
Filtration Options Grease Defined What is in my Kitchen’s Exhaust? Total kitchen exhaust includes all grease particulate sizes as well as grease vapors. Grease is the by-product of commercial cooking processes that must be extracted from the effluent airstream via the kitchen ventilation system. Grease can be broken down into three different categories: • Submicron particles: Produced when a drop of grease or water comes in contact with a hot surface and immediately burns off. Particle sizes range from .

Filtration Options Model Comparison Grease Grabber™ Multistage Filtration System The Grease Grabber dual-stage filtration system uses the Grease-X-Tractor along with the Grease Grabber filter to remove 100% of the grease particles, at 5 microns and larger, out of the airstream. The Grease Grabber filter is designed for heavy-duty grease applications. How it works: The Grease-X-Tractor is the primary filter that removes large grease particles using centrifugal force.
Filtration Options Model Comparison Grease-X-Tractor™ Centrifugal Filtration The Grease-X-Tractor filter is the ideal filter for medium grease loading applications. The design of the filter gives the filter great strength and makes it the best fire barrier in the industry as well as removing 69% of the grease particles at 8 microns. How it works: • The Grease-X-Tractor filter consists of individual vortex chambers having air inlets at the top and bottom front of the filter.
Filtration Options Model Comparison High Velocity Cartridge The high velocity cartridge is designed for light-duty grease applications. How it works: • Exhaust or contaminated air passes through the high velocity stainless steel cartridge. • As the air turns, the particle’s momentum throws the particle out of the airstream as it changes direction, causing the particulates impact upon the cartridge.
Filtration Options Model Comparison Standard Baffle The industry standard baffle filter is designed for light-duty grease applications. How it works: • Exhaust air passes through the aluminum/stainless steel baffles. • As the air turns, the particle’s momentum throws the particle out of the airstream as it changes direction the particulates impact upon the baffles. • The grease then runs down the baffle into the grease trough which drains into a removable grease container.
Filtration Options Applications Grease Extraction by Cooking Equipment Type Different appliances and types of food will produce different amounts of grease. There is a need for different levels of grease extraction efficiency. Accurex recommends filters for each type of cooking equipment. If there is a diverse cooking lineup, use a worse case scenario for the type of filter used. Cooking Equipment Grease Emissions Grease Particulate (lb/1,000 lb.
External Supply Plenums Model Overview Make-up air can be introduced several ways, including through-the-hood with an integrated supply plenum or an external supply plenum. External plenums positioned around the perimeter of exhaust only hoods are a great alternative to integral supply plenums. Unlike integral supply plenums, they do not sacrifice valuable hood containment area. They can also be retrofitted to almost any hood and are generally less expensive than integral plenums.
External Supply Plenums Model Comparison Air Curtain Supply Plenum (ASP) Air curtain supply plenums are typically used in non-tempered or heat-only applications, depending upon climate (can be used as an efficient method for spot-cooling).
External Supply Plenums Model Comparison Variable Supply Plenum (VSP) The variable supply plenum is a versatile plenum combining the features of the face and air curtain supply plenums.

Controls/Energy Management Model Comparison Temperature Interlock. Digital Temperature Interlock The temperature interlock is designed to automatically start the kitchen hood exhaust fans and keep them running while heat is being generated from the cooking appliances. The interlock will override the switch and start the fans once heat is detected in the event an operator fails to turn on the fans manually—ensuring safety and code compliance.
Controls/Energy Management Model Comparison XFCC. Options. Fan Control Center Fan control centers manage the various power connections and relationships to other equipment. This can be a challenge. The Accurex fan control center (XFCC) allows you to manage them from one location, with well-labeled connections and a variety of options to reduce installation and coordination time at the jobsite. (The XFCC is prewired. Minimal field wiring is required for the main power and connection to fans and lighting.
Controls/Energy Management Model Comparison Variable Volume. Variable Volume Saving energy is as simple as recognizing that cooking loads vary throughout the day. Accurex’s Vari-Flow Controls detect these changes in cooking activity and modulate the exhaust and supply air based on demand, thereby saving energy and reducing operating costs.
