FM Series Air Curtain is the use of single-phase capacitor run motor drive, drive shape shapely aluminum tubular wind wheel, or reinforced plastic wind turbine produces episodic airflow distribution, and barrier can reduce indoor and outdoor air convection. Uses its differences FM series air curtain machine: FM series air curtain is suitable for between rooms, between rooms with outdoor air, can be reduced and barrier indoor and outdoor air convection, for every other cold insulation, dust, separated insects, prevent intrusion of harmful gases have played a good role, wide range of applications, such as shopping malls, hotels, restaurants, theaters, hospitals, etc. often open the door, but also applies to the workshop, garage, textile, pharmaceutical and food processing industries . FM-type air curtain without a heater for use in indoor air circulation, RFM is electrical heater, winter temperatures can increase the hallway nearby, prevent or reduce the indoor and outdoor cold air intrusion, summer can turn off the electric heater, single open Fans play the role of FM air curtain. 1, FM150 design installation height should not exceed 3 meters. FM125 type and RFM150 type mounting height should not exceed 2.5 meters. 2, RFM Air Curtain 220-volt and 380-volt two voltage, due to the different line circuit, the device can not interoperable, RFM-1 series and RFM-11 Series Air Curtain, selected according to the user model and control the technical parameters table, equipped with the corresponding conductor cross-section should not be too small due to be equipped with wire, because too much cause accidents. 3, ambient temperature air curtain highest point of use is 50 ℃, no vibration or shock, and no steam droplets splashing, no steam filled the air, non-corrosive gases, non-flammable and explosive places to run in order to ensure the safety of each class air curtain enclosure must be properly grounded. 4, FM-type air curtain is designed with two tranches of wind speed switch, RFM type air curtain which a block is the fan switch and another switch gear is hot, winter and summer, as long as the optional one, you can play a machine with two good results.
