AIRFILTRONIX
Frequently asked questions
Common questions about AIRFILTRONIX from 3G Electric.
What is the difference between AIRFILTRONIX AP and AB series ductless fume hoods?
The AP and AB series differ in what is included with the hood. AP models ship fully assembled with a blower and work surface, but a base or stand is required and not included. AB models include the blower, base or stand, and work surface as a complete package. Both series are available in multiple widths, including 35 3/8 in, 37 3/8 in, and 47 1/4 in, with heights of 37 3/8 in or 4 ft and a depth of 29 1/2 in. Selection depends on whether you already have a suitable support structure or prefer a ready-to-position unit.
How do I choose between carbon, HEPA, and combination filters for an AIRFILTRONIX fume hood?
Filter choice depends on the contaminants being handled. Carbon filters, such as part number 200F CR48P, capture chemical vapors and odors. HEPA filters, such as 200F HP36P and 200F HP48A, capture airborne particulates. Combination carbon/HEPA prefilters, such as 200F FR48A, address both vapor and particulate streams. Filter dimensions must match the hood width: common sizes are 12 in height with widths of 31 1/2 in or 43 1/4 in. Using the correct media ensures the recirculated air meets the intended protection level.
What are the standard dimensions of AIRFILTRONIX ductless fume hoods?
AIRFILTRONIX ductless fume hoods are available in several standard sizes. Common overall widths are 35 3/8 in, 37 3/8 in, and 47 1/4 in. Heights are typically 37 3/8 in or 4 ft, and depth is 29 1/2 in. All units are fully assembled and include a blower. AP models require a separate base or stand, while AB models include the base or stand. These dimensions allow the hoods to fit standard laboratory bench or floor-standing configurations without external ductwork.
Do AIRFILTRONIX ductless fume hoods require external ductwork?
No. AIRFILTRONIX ductless fume hoods are designed to filter and recirculate air within the workspace, eliminating the need for external ductwork. This makes them suitable for locations where installing ducting is impractical, costly, or prohibited by building constraints. The hood draws air through a filter—carbon, HEPA, or combination—and returns cleaned air to the room. Because there is no exhaust duct, the hood can be relocated as needs change, provided the appropriate filter media is used for the contaminants present.
What filter part numbers are available for AIRFILTRONIX fume hoods?
AIRFILTRONIX offers several filter part numbers to match different hood sizes and contaminant types. Carbon filters include 200F CR48P. HEPA filters include 200F HP36P and 200F HP48A. Combination carbon/HEPA prefilters include 200F FR48A. These filters share a common height of 12 in and are available in widths of 31 1/2 in or 43 1/4 in to fit corresponding hood widths. When ordering, confirm the filter part number matches the hood model and the intended application.
Are AIRFILTRONIX fume hoods shipped fully assembled?
Yes. AIRFILTRONIX ductless fume hoods are shipped fully assembled. AP models include the blower and work surface, but a base or stand must be ordered separately. AB models include the blower, base or stand, and work surface. This reduces on-site assembly time and ensures the unit arrives ready for connection to power and immediate use. Verify the specific model's included components before ordering, as configurations vary by part number.
