Powder hods - Type A enclosures provide an effective and safe environment when using powder weighing equipment in conjunction with toxic compounds or chemicals. SafeChange technology minimizes the threat of exposure to toxic powders during pre-filter replacement. The electrostatically charged pre-filter is easily bagged out under negative pressure

• Polycarbonate and custom-blend polypropylene construction materials.
• Rolled unibody design enhances stability.
• Plastic blower plenum reduces vibration and deadens noise.
• Ergonomic spill basin for powder or liquid spills.
• Built-in slip hatches for Electrical cords.
• Full access folding sash.

The AirMax total exhaust laboratory fume hoods are manufactured from structural polypropylene, which eliminates the potential for corrosion. Featuring the standard bypass design, AirMax exhausts a constant volume of air regardless of sash position. Optional features are available for precise control of blower speed and face velocity.

The AirMax microprocessor controller monitors face velocity and displays real-time airflow on the LCD screen in linear feet per minute. Blowers can be turned on/off via the AirMax controller when fitted with the VSD1 (variable speed driver).

Standard Features

• AirMax microprocessor controller.
• Constant monitoring of fume hood face velocity with variable airflow control to user- preset value.
• Dual- wall construction allows for front mounting of services, such as water, gas, or electricity.
• FlowSmooth airfoil on sash lip promotes consistent laminar airflow.
• Integral vapor-proof fluorescent lighting.
• Lab event timer.
• Polypropylene construction for chemical resistance for achieving zero rust.
• Vertical sliding safety glass sash.

Walk-in hoods are available in standard lengths of 4ft to 8ft. However, they can also be built to suit custom sizes, depending on the lab space requirements. Their exterior panels are phosphate coated with a baked chemical resistant and synthetic resin finish; and are constructed with heavy gauge, cold rolled steel. They are available in vertical and horizontal sash types, radiused corner posts and air foils for smooth air movement, thereby, assuring high levels of comfort, safety and efficiency

Walk-in hoods are used where a taller apparatus is required or when equipment is rolled into the hood. These hoods provide a minimum 78" of interior working height. These hoods are designed and tested to meet ASHRAE 110-2016, BS 7258 and DIN 12.924 standards. Some of the salient features are listed below:

• Radiused corner posts and air foils for smooth air movement, assuring high levels of comfort, safety and efficiency
• 4" thick end walls provide more interior work space and a clean-lined, uncluttered design
• Interior baffles designed to minimize turbulence and optimize containment
• Frameless sashes with full-length steel handle for neat, clean appearance and streamlined features
• Low profile PVC sash tracks and exclusive sash levelling and alignment features assure an easy and smooth sash operation
• Large friction-fit interior access panels provide easy access to piping and service fittings
• Heavy gauge cold rolled steel exterior panels with independent rigid structural frame
• Designed and tested using ASHRAE 110-2016, EN-14175-3, BS 7258, and DIN 12924 Standards

Custom hoods and enclosures are specifically engineered to meet customer specific applications and requirements. From modifying a simple front open space to accommodating any specific equipment like reactors and pilot plant enclosures, Kewaunee's technical team can work with the clients team to design and identify the right fume hood apt for the application.

The Kewaunee team designs and builds the product, and then extensively tests the actual hood at the factory for containment and other standard tests. Further, clients are recommended to witness the ASHRAE tests conducted under factory conditions.

Kewaunee also conducts comprehensive ASHRAE 110 tests together with velocity and/or smoke tests after the hoods are installed at the customers project site.

Kewaunees latest innovation, the highly efficient Supreme Air LV fume hood offers unsurpassed safety, a host of user-friendly features, and a substantial 45% energy savings over standard fume hoods.

The safety and ergonomic features include:

• Full containment at all sash positions, based on ANSI Z9.5 recommended levels
• Smooth operating, 18" auto-return, belt-drive sash
• Optional automatic sash operator
• Obstruction-free flush sill
• Rear-outlet, front-mounted, anti-splash cup sink
• Staggered service outlets
• Angled access panels with Gaskets
• Cord pass-through
• Easy-to-clean baffle system

Kewaunees LCV fume hood is designed under the proven constant volume technology that avoids requirements of expensive and high maintenance alternatives. LCV fume hood requires over 70 percent less exhaust air volume than a traditional by-pass fume hood. This design conserves natural resources while saving thousands of dollars per fume hood on:

• Initial HVAC requirements
• Annual energy consumption

LCV fume hoods are vigorously tested to meet ANSI / ASHRAE 110-1995 guidelines. In addition, they have been subjected to stringent dynamic testing, including walk-bys, cross-drafts, and multiple breathing zone challenges, while maintaining unsurpassed containment.

LCV fume hood design features:

• Engineered for safety and convenience.
• Low profile sash frame for easy access through horizontal panels.
• Flush sill for unobstructed access through vertical opening.
• Double vertical sash design allows full view into hood interior and 37 opening height for apparatus setup.
• Service ports provide convenient, safe passage for equipment connections.
• Exclusive Air Alert 500 alarm provides a visual one-hour timeline of fume hood performance.
• Exclusive static pressure averaging mechanism provides accurate face velocity readings regardless of sash positioning.
• Quiet fume hood operation, under 40 dBA!
• UL listed when pre-wired per UL 3101-1 1993.

fume hoods are designed for the needs of new generation scientists, combining safe and energy efficient designs with a multitude of user-friendly features. Designed on a rigid frame construction that assures solid installation, low vibration and sound levels, kewaunee fume hoods provide a reliable and efficient operation with the highest levels of safety. (all kewaunee fume hoods are tested using ashrae 110-2016 and en-14175-3 standards.)
