48" Wide Vented Balance Enclosure Overview
The 48" Wide Vented Balance Enclosure (Yamato Scientific model VBE408) is a self-contained ductless workstation built for weighing fine powders, chemicals, and biological products. Its 48" exterior width and 47.25" interior span frame an optically clear acrylic chamber. Top-mounted HEPA/blower filtration recirculates chamber air through the filter and back into the lab. LabSupplies.com stocks this unit as an authorized Yamato Scientific dealer.
Construction centers on optically clear 3/8" jeweled acrylic plastic for full-visibility containment. A phenolic base resists chemicals, stabilizes analytical balances, and dampens vibration; its black finish makes stray powder easy to spot. Curved ABS airfoils route gentle, unobstructed flow through rear and side baffles toward the top-mounted HEPA filter.
Power runs on 115–120V, with a 220–240V variant (VBE418) available for high-voltage sites. Interior working space measures 47.25" × 23" × 21.5", inside a 48.5" × 26.75" × 41" exterior footprint. Manufactured in the USA, the enclosure ships at 350 lbs and carries CE certification with a Declaration of Conformity.
Key Features
- HEPA/blower filtration: top-mounted aluminum-frame H14 HEPA with 100 mm pleat, rated 99.9997% at 0.3 microns, sealed by upstream and downstream polyurethane gaskets.
- Phenolic base: superior chemical resistance, analytical-balance stabilization, and low vibration; black finish makes spilled powder easy to detect.
- Face-velocity alarm: 40–2000 fpm range with sub-1-second response, LED and audible Piezo, plus green (healthy), yellow (turbulence), and red (system failure) indicators.
- Viewing sash: front sash with multiple air foils that raise containment and deflect drafts, backed by adjustable front draft protection.
- Acrylic chamber: optically clear 3/8" jeweled acrylic plastic delivers full operator visibility into the work zone.
- Expandable ports: electrical cord outlet port plus a side blank plate ready for an optional Bag-In/Bag-Out port.
How to Choose the Right Vented Balance Enclosure
Match the enclosure to your balance, your throughput, and your facility power . Use these axes to confirm fit.
- Chamber size: verify your balance and sample handling fit the 47.25" × 23" × 21.5" interior and that the 48.5"-wide exterior clears your bench or floor space.
- Voltage: select VBE408 for 115–120V sites or VBE418 for 220–240V infrastructure, since the blower draws on the building circuit.
- Filtration class: H14 HEPA suits fine powders and biological products; confirm the 99.9997% efficiency aligns with your containment policy.
- Base material: a phenolic base resists chemicals and steadies analytical weighing, which matters for vibration-sensitive measurements.
- Airflow monitoring: a face-velocity alarm with visual and audible alerts confirms safe operation and flags turbulence or failure in real time.
- Future expansion: the side blank plate lets you add a Bag-In/Bag-Out port if hazardous-material handling scales up.

Frequently Asked Questions
What voltage options are available for the 48" Vented Balance Enclosure?
Two voltages are available. VBE408 runs on 115–120V and VBE418 runs on 220–240V; both share identical chamber dimensions, filtration, and construction.
What are the interior working dimensions?
Interior working space measures 47.25" × 23" × 21.5" (1200 × 584 × 546 mm). The exterior footprint is 48.5" × 26.75" × 41" (1232 × 679 × 1041 mm).
What type of filtration does this enclosure use?
It uses a top-mounted HEPA/blower system with an aluminum-frame H14 HEPA filter rated 99.9997% at 0.3 microns. Air recirculates through the filter and back into the lab, so no ductwork is required.
What materials are used in construction?
The chamber is optically clear 3/8" jeweled acrylic plastic, and the base is phenolic. The phenolic base provides chemical resistance, balance stabilization, and a black finish that makes powder easy to detect.
How does the airflow alarm work?
A face-velocity alarm monitors flow across a 40–2000 fpm range with sub-1-second response. LED and audible Piezo indicators show green for healthy flow, yellow for turbulence, and red for system failure.
What is the difference between VBE408 and VBE418?
The only difference is power supply. VBE408 is the 115–120V model and VBE418 is the 220–240V model; chamber size, HEPA filtration, phenolic base, and alarm are the same on both.
