HEMCO
Frequently asked questions
Common questions about HEMCO from 3G Electric.
What materials are HEMCO fume hoods constructed from?
HEMCO fume hoods are available in stainless steel or fiberglass with a gel-coated finish. Stainless steel models, such as those with chrome-plated housings, offer corrosion resistance and are suitable for use with hot plates or portable equipment. Fiberglass gel-coated units provide chemical resistance and are lighter in weight. The choice of material depends on the specific application and the types of substances being handled.
Do HEMCO canopy hoods come with a blower included?
No, HEMCO canopy hoods and instructional ducted fume hoods are typically supplied without a blower. For example, models like the CE Ducted Fume Hood (MPN 14841) and the UniFlow LE AireStream (MPN 35661) require a separate blower for operation. This allows the end user to select a blower that matches the ductwork and exhaust system requirements of their facility.
What is the airflow range for HEMCO fume hoods available from 3G Electric?
HEMCO fume hoods stocked by 3G Electric have airflow ratings ranging from 750 CFM to 1500 CFM. For instance, the stainless steel canopy hood model MPN 13130 is rated at 750 CFM, while models MPN 13160 and 23160 are rated at 1500 CFM. These ratings are based on standard configurations and may vary with ductwork and blower selection.
What type of lighting is used in HEMCO fume hoods?
HEMCO fume hoods feature vapor-proof lighting systems. Many models include vapor-proof LED light fixtures with control switches, as seen in the UniFlow LE AireStream series (MPN 35661). Other models use standard vapor-proof lights. This design ensures safe operation in environments where flammable vapors or dust may be present.
Are HEMCO instructional ducted fume hoods suitable for educational laboratories?
Yes, HEMCO instructional ducted fume hoods, such as the CE series (MPN 14841 and 13041), are designed for educational settings. They feature by-pass airflow designs and include vapor-proof lights. These hoods are available in widths of 30 inches and 4 feet, with 24-inch depths, making them suitable for benchtop use in teaching labs. They require a separate blower and do not include a base or work surface.
What is the overall depth of HEMCO canopy hoods?
HEMCO canopy hoods available from 3G Electric have an overall depth of 30 inches. This applies to models such as the stainless steel fume hoods (MPN 13130, 13140, 13160, 23160) and the fiberglass ducted hood (MPN 23060). The 30-inch depth provides adequate coverage for benchtop equipment like hot plates or portable devices.
