Biological Safety Cabinet ClassII Type A2

Product Description

YAKOS 40 Years of Manufacturing Experience
SAFZONE® Biosafety Cabinet is a safety device to protect the operator, product and environment. It is designed to work with agents that require Biosafety Level 1 ~ 3 containment, such as biohazardous agents, nature microbial strains and clinical diagnostic inspection samples. It is made to meet the specific requirements of NSF49 and EN12469. SAFZONE® Biosafety Cabinet can help to avoid exposure to possible infectious aerosols and spills during the operation.

Product Details

Specification

SAFZONE^® Class II type A2 Biosafety Cabinets maintain negative pressure environments inside the cabinet to prevent the contaminants from escaping the work area to protect the operator. Approximately 70% of the room air is pressurized by the blower and forced through the supply HEPA filter prior to entering the work area, to protect the product. Finally, the remaining 30% of air is filtered through an exhaust HEPA filter. The sterile air finally exits the cabinet and is released back into the room to protect the environment.
As a trusted brand, YAKOS’s products and services continue to be strictly regulated and our high quality manufacturing facilities have been specifically used for the development of BSC products. SAFZONE® Biosafety Cabinets undergo thorough quality testing before being released, to ensure consistent quality for your piece of mind.
YAKOS is devoted to maintaining the highest standards and professional certifications attainable in the industry. SAFZONE® Biological Safety Cabinets have been designed, manufactured and tested to comply with the following standards and regulations to provide the highest level of protection for operator, product and environment when working at biosafety level 1, 2 and 3.

Maximum Protection for Operator, Product and Environment

Double-wall structure surrounded with negative pressure to fully prevent leakage of contaminated air in the event of damage to the cabinet external walls.

SAFZONE^® Biosafety Cabinets create inflow to protect the operator, HEPA-filtered laminar downflow for product protection and exhaust air from cabinet through HEPA filter for environmental protection. SAFZONE^® Biosafety Cabinets can prevent the aerosols generated during operation from harming the external environment or the operator itself and can also reduce cross-contamination between products due to aerosols.

	Out of balance tests performed at ±10 fpm nominal set points for both inflow and downflow, SAFZONE Biosafety Cabinets still maintain an excellent enclosure for operator & product protection biological challenge tests as well as smoke patterns tests.
	Surround air intake grille design－All contaminated air is isolated inside the cabinet to maximize the Biosafety Cabinet protective capabilities. It prevents aerosols, vapors and particulates escaping into the operator’s environment from the front opening or window sash edges of cabinet.
	Inward airflow of 0.51 m/s velocity to the open front for operator protection.
	The Supply HEPA filter provides ISO Class 4 (per ISO14644.1) clean air to the work area in a gentle vertical laminar flow, for product protection.

QUALITY & PERFORMANCE GUARANTEE
A Factory Testing Report will be enclosed with each SAFZONE^® Biosafety Cabinet.
The following performance and safety tests being conducted before leaving the factory.

Pressure decay test	Lighting intensity test
HEPA filter leak test	Vibration test
Inflow velocity test	Noise level test
Downflow velocity test	UV lighting intensity test
Airflow smoke patterns test	Electrical safety test

CONTROL SYSTEM SELECTION
Modular electronic components and neat wiring layout applied on SAFZONE^® Biosafety Cabinets to simplify the maintenance work. Electronic parts are easily accessible and easy to reach for the operator from the drop down control panel. Control systems and pipelines completely isolated from contaminated areas for convenient and safe maintenance.
7 Inch HMI Touch Screen

Advanced Human Machine Interface (HMI) Touch Screen mounted on SAFZONE^® BSCs to

provide user with a better graphic view for easy operation and function settings and continuous displays the cabinet’s performance.
♦ High resolution LCD display visualizes operating, monitoring and efficient control in real time.
♦ The large 7 inch full color touch screen enables intuitive parameter entry and displays variable data,
including trend graphs and alarm elements.
♦ User-friendly visual icons quickly creates users an “easy-to-navigate” to make operation more efficient.
♦ Display real time clock and date, inflow, downflow, negative plenum pressure, HEPA filter running hrs,
UV lamp running hrs at the front page.
♦ Main functions include:

– Automatic Pre-purge / Post-purge
– Built-in timer for counting up and down, UV light
– Safety interlock for window and UV light to protect the operator from UV irradiation
– Audible and visual text alarms for the following abnormal situations:
■ High / Low inflow velocity
■ High / Low downflow velocity
■ Wrong window operation height
■ High negative plenum pressure
■ Usage time of HEPA filter exceeds the setting hour HEPA
■ Usage time of UV lamp exceeds the setting hour UV
– Operation records including Inflow, Downflow and Pressure
– Multi-language display settings
– Two kind of unit display settings for air velocity and pressure

Membrane Switch Control Panel with Pressure Gauge

Membrane Switches are easy to use. Built-in UV light timer for 0~99 minutes / hours and negative plenum pressure gauge.
Safety interlock device controls blower, fluorescent light and UV light on/off by window sash open and closed.

WINDOW ALARM	When the window is not at the operation height, it will release an audible and visual alarm automatically.
MUTE SWITCH	When the alarm is activated, it can be muted temporarily while the alarm light continues to flash. If the abnormal situation has not been settled, the cabinet alarm will be activated again within a set time (5 minutes) to alert the operator.
SAFETY INTERLOCK	When the window is opened, the blower and fluorescent light will be activated automatically and the UV light will be switched off. When the window is fully closed, the UV light will be re-activated automatically. The blower and fluorescent light will be switched off.
UV LIGHT TIMER	Built-in UV light timer for 0~99 minutes / hrs.
PRESSURE GAUGE	Displays the negative plenum pressure of the cabinet in the unit of mm Aq.
