A clean bench, vertical air stage works, the air through the top / rear of the early effect of air filters and low-noise centrifugal fan pressed into the plenum chamber, the high efficiency air filters uniformly blown on the side to form a high level of cleanliness / vertical air curtain to remove the original natural air in the work area, five minutes after power to achieve the desired high purity space. Two-speed fan with adjustable air volume adjustment, touch-type switching regulator voltage, to ensure the wind speed in the work area is always in perfect condition. Second, the structural features of the housing shell imported MDF sheets seamlessly combined to ensure the long-term no corrosion occurs, the surface layer is electrically spraying the surface treatment, surface smooth clean the platen laying stainless steel, convenient and durable. Third, the technical specifications of the SW-CJ-1F / 1FD SW-CJ-2F / 2FD cleanliness class 100 @ ≥0.5μm ≤0.5 colonies / plate. When (Φ90㎜ culture dish) average wind speed 0.25m ~ 0.45 / m / s (fast and slow two-speed) Noise ≤62dB (A) Vibration half peak ≤0.5μm (xyz direction) Illumination ≥300LX single-phase AC power supply 220V / 50Hz Maximum power consumption 400W 800W Weight <150㎏ <250kg efficiency filter specifications and the number 865 × 558 × 50 × ①? 1355 × 558 × 50 × ① Fluorescent / UV lamp specifications and quantity of 20W × ① / 20W × ① 30W × ① / 30W × ① applicable number of single-sided single-sided double-sided double-sided Dimensions 1050 × 680 × 1600 mm 1540 × 680 × 1600 mm work area size 870 × 700 × 1360 × 650 × 520㎜ 520㎜ Description: We accept customer specifications requirements of the non-standard type clean bench (according to user needs with UV light disinfection function) Fourth, the installation location of the bench in place should be relatively clean working environment indoor (preferably placed one hundred thousand Level three hundred thousand clean room or junior level), plug in the power, according to the functions shown on the control panel to open, before turning to deal with the clean bench workspace surface and shell carefully cleaned to remove surface dust boot After ten minutes can be implemented to normal operations. V. Maintenance 1, according to the actual situation, periodically remove the primary filter cleaning, cleaning cycle is generally three to six months. (If long periods of cleaning, dust will lead to insufficient intake air volume decreases cleaning effect). 2, when the normal replacement or cleaning early efficiency air filters, still can not achieve the desired cross-section wind speed, the operating voltage of the fan should be adjusted to achieve the desired average wind speed. 3, usually after ten months when the fan using the operating voltage is adjusted to the highest point, still can not achieve the desired speed, then the high efficiency air filter too much dust (filter on the filter holes basically blocked in a timely manner update), the general HEPA filter use period of eighteen months. 4, replacement of high efficiency air filters, be aware of the correct type and size of (the original manufacturer configuration), press the arrow wind devices, and pay attention to the filter perimeter seal, absolutely no leakage occurred. Sixth, the general cause of the malfunction and troubleshooting Symptom Cause Remedy main power switch and not on automatic trip 1 fan stuck causing the motor to stall, or line short circuit. 1. Adjust the fan shaft position, or replace the impeller and bearings, check the line is intact. ? 2, the control circuit diagram of spot-checking circuit, components of the shell insulation resistance, repair the insulation fault location. Winds from the low efficiency filter dust early 1. Excessive 2. Efficient filter failure 1. Clean primary filter. 2. Replace the high efficiency filter. Fan does not turn 1. Contact 2. Fan power does not work fuse has blown 1. Check the contactor wiring is correct. 2. Replace the fuse. Fluorescent lamp does not light or relay damage 1. 2. Lamp power fuse has blown 1. Replace the lamp or relay. 2. Replace the fuse.
