Kewaunee 8' Supreme Air Chemical Fume Hood Overview

The Kewaunee Supreme Air series has long been recognized for providing dependable laboratory containment through carefully engineered airflow management and durable construction. This 8-foot model features a full-width vertical rising sash that provides excellent visibility into the work area while allowing laboratories to accommodate taller glassware, analytical instruments, reactors, and experimental apparatus. Aerodynamic airfoils and multiple exhaust baffles promote uniform airflow throughout the hood interior to help improve containment and reduce turbulence during normal laboratory operation. The spacious work area makes this hood particularly well suited for large-scale chemistry, synthesis, distillation, and pilot-scale research applications. Kewaunee Supreme Air fume hoods are designed and tested to recognized laboratory ventilation standards, including ASHRAE 110 performance testing.

Common Applications for the Kewaunee 8' Supreme Air Chemical Fume Hood

The Kewaunee Supreme Air is commonly used for chemical synthesis, solvent handling, acid digestion, reagent preparation, pharmaceutical formulation, analytical chemistry, sample extraction, distillation, titration, quality control testing, and general laboratory procedures involving hazardous vapors or airborne contaminants. The generous 8-foot work surface allows multiple users or large experimental setups to be accommodated safely within a single containment enclosure.

Ideal Lab Types for the Kewaunee 8' Supreme Air Chemical Fume Hood

This chemical fume hood is well suited for pharmaceutical manufacturers, biotechnology companies, university research laboratories, chemical manufacturing facilities, environmental testing laboratories, forensic laboratories, industrial quality control departments, and government research institutions. Laboratories utilizing analytical balances, hotplate stirrers, laboratory ovens, reactors, water purification systems, and chemical storage cabinets frequently incorporate large chemical fume hoods into their laboratory workflows.

Refurbishment and Testing Process

At American Instrument Exchange, each refurbished chemical fume hood is inspected prior to shipment. The hood structure, sash assembly, counterweight system, and interior liner are evaluated for condition and functionality. The vertical sash is inspected to verify smooth travel and proper counterbalance operation. Cosmetic cleaning and general refurbishment are completed before shipment. Final installation, exhaust connection, and airflow certification should be performed by qualified personnel at the customer's facility to verify compliance with local codes and laboratory safety requirements.

Shipping and Installation Considerations

Because of its size, the Kewaunee 8' Supreme Air Chemical Fume Hood ships via freight and should be installed by qualified personnel familiar with laboratory ventilation systems. Buyers should verify doorway clearances, laboratory dimensions, exhaust duct compatibility, electrical service requirements, and utility connections before delivery. Following installation, the hood should be certified according to applicable laboratory ventilation standards before being placed into service. American Instrument Exchange can also provide biosafety cabinet certification, ASHRAE testing, and laboratory equipment services through AIE Laboratory Services for customers throughout New England.

Related Laboratory Equipment

Laboratories purchasing chemical fume hoods often also require biosafety cabinets, laboratory casework, chemical storage cabinets, analytical balances, hotplate stirrers, laboratory ovens, water purification systems, and centrifuges. American Instrument Exchange offers a wide selection of refurbished laboratory equipment to support chemistry laboratories, pharmaceutical manufacturing, biotechnology research, environmental testing, and industrial quality control applications.

Kewaunee 8' Supreme Air Chemical Fume Hood Frequently Asked Questions

What is the advantage of a vertical rising sash?

A vertical rising sash provides unobstructed access across the full width of the hood while maintaining an effective containment barrier. It is especially useful when working with tall laboratory equipment, reaction vessels, or large experimental apparatus.

How is this hood different from a combination sash model?

This unit features a full vertical-rising sash only. Unlike combination sash models that include horizontal sliding panels, the single vertical sash provides maximum opening width and simplified operation while maintaining excellent visibility into the hood interior.

Does the hood include plumbing and electrical fixtures?

Utility fixtures, lighting, and countertops may vary depending on the individual unit. Buyers should review the photographs and specifications or contact American Instrument Exchange to verify the exact configuration prior to purchase.

Does the fume hood require certification after installation?

Yes. Like all laboratory chemical fume hoods, the unit should be installed, balanced, and certified by qualified laboratory ventilation professionals before routine laboratory use to verify proper airflow and containment performance.

What warranty is included?

This refurbished Kewaunee 8' Supreme Air Chemical Fume Hood includes a 90-day warranty from American Instrument Exchange.

Testing Procedures for Used and Refurbished Laboratory Equipment

Ensure Accuracy, Safety, and Dependable Performance Across Applications

At American Instrument Exchange, all used and refurbished laboratory equipment undergoes a rigorous, multi-point testing protocol to ensure optimal performance, operational safety, and long-term reliability. Whether the equipment is destined for research, diagnostics, quality control, or production environments, our thorough inspection and testing process is designed to meet the highest standards of laboratory excellence.

Why Testing Used Lab Equipment Is Essential

Before any refurbished laboratory equipment is returned to service, it must be carefully tested to verify:

• Functional integrity and operational performance
• Setpoint accuracy and repeatability (where applicable)
