The Haier HR900-IIA2-N is a 3-foot Class II Type A2 biological safety cabinet, NSF/ANSI 49 certified, providing the three-way protection — personnel, product, and environment — that microbiology, cell culture, and clinical work with BSL-1 and BSL-2 agents require. A Class II Type A2 cabinet recirculates 70% of airflow as downflow and exhausts 30% through ULPA filtration, protecting both the operator (via the inflow air curtain) and the sample (via HEPA/ULPA-clean downflow). The HR900-IIA2-N uses ULPA U15 filters rated 99.9995% at 0.12 µm on both main and exhaust paths, an energy-efficient DC blower, and a universal 100–230 V input.

Application Profile
The HR900-IIA2-N is the compact 3-foot footprint in Haier's NSF Type A2 line, sized for a single operator or a bench where floor space is limited but true containment is required. As a Class II Type A2 cabinet it is appropriate for work with microbiological and biomedical agents at BSL-1 and BSL-2 — cell and tissue culture, microbial handling, and clinical sample processing — where the ULPA-filtered downflow protects the product and the inward air curtain protects the operator. It is not designed for volatile toxic chemicals or radionuclides unless ducted appropriately; the A2 class is for biological, not chemical, containment. (See containment-classes.)
A comprehensive alarm set — abnormal inflow, abnormal downflow, filter clogging, filter damage, door-open-beyond-limit, filter and UV-lamp lifetime — makes the cabinet's protective state continuously visible, and a UV lamp supports surface decontamination between sessions. Optional GFCI sockets, side-wall service taps (gas, vacuum, air, water), a 316-SS work surface, and an antimicrobial coating tailor the cabinet to specific workflows.
Frequently Asked Questions
What containment class is the Haier HR900-IIA2-N? It is a Class II Type A2 biological safety cabinet, NSF/ANSI 49 certified, providing personnel, product, and environmental protection for BSL-1 and BSL-2 work.
How big is the 3-foot model? Internal work area is 930 × 600 × 650 mm (nominal 3 ft width); external dimensions are 1040 × 850 mm wide × 2160 mm tall including the cabinet body.
What filters does it use? ULPA U15 filters rated 99.9995% efficient at 0.12 µm on both the main (downflow) and exhaust paths, with a 70% downflow / 30% exhaust airflow split.
Can I use it for chemical fumes? No — a Type A2 cabinet is for biological containment. It should not be used for volatile toxic chemicals or radionuclides unless properly ducted; consult the containment-class guide before specifying.
What power does it need? A universal 100–230 V, 50/60 Hz input (1300 VA); the US configuration uses 115 V or 220 V/60 Hz taps within that range.
Ordering & Configuration
quote-based. The HR900-IIA2-N is a capital biosafety cabinet sold through a quote. At quote we confirm the electrical service and receptacle, floor space and ceiling clearance for the 2160 mm cabinet height, the support stand (standard 680 mm or optional adjustable), any side-wall service taps, sockets (optional GFCI), work-surface and coating options, and certification/field-validation needs. Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the HR900-IIA2-N for your lab.
Sizing the NSF Type A2 line: the HR900-IIA2-N is the 3-foot cabinet for single-operator or space-limited benches. Step up to the HR1200-IIA2-N (4 ft), HR1500-IIA2-N (5 ft), or HR1800-IIA2-N (6 ft) for wider work areas and multi-operator use. Pair the 4-foot cabinet with the matching adjustable Stand-4FT.
