The Haier HR1500-IIA2-N is a 5-foot Class II Type A2 biological safety cabinet that protects the operator, the sample, and the environment during work with biohazardous materials — verified to NSF and UL. Dual DC centrifugal fans, ULPA U15 filtration capturing 99.9995% of 0.12 µm particles, and a hot-ball anemometer that actively holds airflow constant make it a core containment tool for microbiology, cell culture, and clinical labs.

Application Profile
A Class II Type A2 cabinet is the workhorse of biosafety containment: it provides personnel, product, and environmental protection for work with agents up to Biosafety Level 2 (and BSL-3 with appropriate facility controls). The HR1500-IIA2-N delivers that with a 70% recirculated / 30% exhausted airflow pattern, an inflow of 0.53 m/s that guards the operator at the sash opening, and a laminar 0.35 m/s downflow that protects the work. ULPA U15 filters on both the supply and exhaust intercept 99.9995% of 0.12 µm particles — a step beyond typical HEPA — so the air over the work surface and the exhaust to the room are ultra-clean.
What keeps that protection constant is the hot-ball anemometer: it monitors downflow and inflow velocity in real time and the microprocessor adjusts fan speed to hold the setpoint as filters load, rather than letting protection drift. A one-piece welded cabinet with stainless liner and work surface prevents leakage per NSF specification, and the 10° ergonomic inclination improves posture and sight lines for long sessions.
Design Architecture
The digital LCD screen reports running status and drives a comprehensive alarm and monitoring set: abnormal inflow, abnormal downflow, door/sash open beyond limit, filter clogging, filter damage, filter lifetime, and UV lamp lifetime, with sound-and-flash alerts and a fan interlock when the door opens. A UV lamp with a programmable 0–24 hour timer handles surface decontamination, two waterproof sockets (optional GFCI) with timing support in-cabinet equipment, and an optional 680–900 mm adjustable-height stand sets working height. Universal casters with built-in threaded support feet ease positioning and leveling.
Frequently Asked Questions
What class and type is the HR1500-IIA2-N? Class II, Type A2 — providing operator, product, and environmental protection, with 70% air recirculated and 30% exhausted through ULPA filtration.
What size work opening does it have? A 5-foot cabinet (1530 mm interior width) with a 200 mm working sash opening (460 mm maximum).
How is protection kept constant as filters age? A hot-ball anemometer measures airflow in real time and the microprocessor adjusts fan speed to maintain the set velocities, alarming if inflow or downflow goes abnormal.
What filtration does it use? ULPA U15 main and exhaust filters, capturing 99.9995% of particles at 0.12 µm.
Is it certified? Yes — UL and NSF certified.
Ordering & Configuration
The HR1500-IIA2-N is a capital purchase: request a quote for pricing, freight, siting, and field certification planning. As a containment device it should be professionally installed and NSF/field-certified on site. Backed by Haier Biomedical's manufacturer warranty — confirm current terms and lead time with your quote.
Choose the 5 ft HR1500-IIA2-N when a single or two-person Class II Type A2 workstation fits your bench run and BSL-2 (or BSL-3 with facility controls) work. Step to the 6 ft HR1800 for more working width, or a 3–4 ft HR900/HR1200 for compact spaces; pair with the matching adjustable stand for correct working height.
