The Haier HR1200-IIA2-N is a 4-foot Class II Type A2 biological safety cabinet providing personnel, product and environmental protection for work with biological agents up to Biosafety Level 3 (with facility measures). With a 1230 mm (4 ft) internal work width, ULPA U15 filtration and a 70% recirculated / 30% exhausted airflow pattern, it is UL and NSF certified for microbiological and cell-culture work in clinical, research and diagnostic labs. It is the standard-width cabinet most labs specify when they need a certified Class II A2.

Application Profile
A Class II Type A2 cabinet protects three things at once: the operator (via an inflow air curtain at the sash), the sample (via ULPA-filtered downflow), and the room and environment (via ULPA-filtered exhaust). The HR1200-IIA2-N implements this with a 70% downflow / 30% exhaust split, a 0.35 m/s downflow and a 0.53 m/s inflow — the balance NSF/ANSI 49 defines for A2 cabinets — and both the supply and exhaust air pass through ULPA U15 filters rated 99.9995% at 0.12 µm, a step finer than standard HEPA. Because it is a Type A2, a properly functioning cabinet can be recirculated into the room or canopy-connected for light volatile use per your biosafety plan.
The cabinet is engineered for safe, ergonomic daily use. A comprehensive alarm set — sound and flash for door-ajar, abnormal inflow, abnormal downflow, filter clogging, filter damage, filter lifetime and UV-lamp lifetime — keeps the operator informed of containment status, and the sash operates to a 200 mm working height (460 mm maximum). Two electrical sockets (optional GFCI), an armrest for comfort, an integral UV lamp and a one-piece work surface round out a 4-ft footprint that fits most standard lab benches and doorways. It carries UL and NSF certification, the baseline most institutions require.
Frequently Asked Questions
What class of biosafety cabinet is the HR1200-IIA2-N? It is a Class II Type A2 cabinet — providing personnel, product and environmental protection with 70% recirculated / 30% exhausted airflow.
What size is it? Nominally 4 feet, with a 1230 mm internal work width — the standard-width Class II cabinet for most benches.
What kind of filters does it use? ULPA U15 filters (99.9995% efficient at 0.12 µm) from AAF on both the downflow and exhaust — finer than standard HEPA.
Is it certified? Yes — UL and NSF certified. Field certification to NSF/ANSI 49 after installation is recommended as with any Class II cabinet.
Can it handle volatile chemicals? As a Type A2, only light/trace volatile use is appropriate, and only when canopy (thimble) connected to exhaust per your biosafety plan. It is not a substitute for a Type B2 total-exhaust cabinet or a fume hood.
Ordering & Configuration
The HR1200-IIA2-N is a capital purchase. Add it to a quote and a Legacy Lab Supplies specialist will confirm width/siting, electrical service, stand and service-tap accessories, and post-install NSF field certification before order, and route warranty registration. Lead time is quoted per configuration; contact us for current availability.
Choose the HR1200-IIA2-N as a certified 4-ft Class II A2 cabinet for general microbiology and cell culture. Need more or less bench width? The HR900 (3 ft), HR1500 (5 ft) and HR1800 (6 ft) share the same platform. Pair it with an adjustable stand and optional service taps (petcocks) to complete the install.
