Frequently asked questions
Common questions about AIR SCIENCE from 3G Electric.
What materials are AIR SCIENCE spill trays and work surfaces made from?
AIR SCIENCE spill trays and work surfaces are constructed from polypropylene, a thermoplastic polymer known for its chemical resistance and durability. Polypropylene is suitable for containing spills of many acids, bases, and solvents commonly used in laboratories. The material is non-porous, easy to clean, and resistant to corrosion. For example, the TRAY-P5 series spill trays and TRAY-P10, TRAY-P30, and TRAY-P40 work surfaces are all polypropylene. These components are designed to fit specific AIR SCIENCE fume hood models, such as the Purair 10, 30, and 40 ductless hoods.
Are AIR SCIENCE portable fume extractors compatible with ductwork?
AIR SCIENCE portable fume extractors, such as the VE-FES-M-A model, are designed as vented enclosures that do not require a blower or external ductwork. They are self-contained units with integrated filtration, typically using a polyester pre-filter and additional filter media. The analog display indicates operational status. These units are intended for localized exhaust of fumes at the point of use, making them suitable for applications where fixed ductwork is impractical. For ducted systems, AIR SCIENCE offers vent-box filtration units like the VB60-A, which require an external blower.
What is the typical voltage requirement for AIR SCIENCE vented enclosures?
AIR SCIENCE vented enclosures, including portable fume extractors and vent-box filtration units, are commonly available in 115V AC configurations. For example, the VE-FES-M-A fume extractor and VB60-A vent-box unit both operate at 115V AC. This voltage is standard for laboratory equipment in many regions. Buyers should verify local electrical standards and ensure compatibility with their facility's power supply. Some models may be available in other voltage options; consult the product datasheet for specific electrical ratings.
How do I select the correct AIR SCIENCE spill tray for my fume hood?
To select the correct AIR SCIENCE spill tray, match the tray's overall width and length to the fume hood's interior dimensions. For example, the TRAY-P5-24 (24 in wide, 24 in long) is compatible with the P5-24-XT-G hood, while the TRAY-P5-36 (24 in wide, 36 in long) fits the P5-36-XT-G. The TRAY-P5-48 (24 in wide, 48 in long) is for the P5-48-XT (RX)-A. These trays are designed to sit inside the hood's work area to catch spills. Always verify the manufacturer part number and compatible model number from the product listing to ensure proper fit.
What filter types are used in AIR SCIENCE ductless fume hoods?
AIR SCIENCE ductless fume hoods, such as the Purair series, use a combination of pre-filters and main filters. Pre-filters are typically made of polyester and capture larger particulates to extend the life of the main filter. Main filters can include activated carbon for organic vapors, HEPA for particulates, or specialized media for specific chemicals. The exact filter type depends on the application and the hood model. Filter replacement intervals vary based on usage and contaminant load. Consult the hood's manual or 3G Electric for filter specifications and replacement parts.
