(G3, G4 )Pre Filter- Auto-Roll Type Air Intake Filter Automatic Roll Air FilterPRODUCT INTRODUCTIONFrame material: Powder coating galvanized steel sheets/Stainless steel Filter media: Polyester synthetic fiber,G3, G4 (EN779) efficiency Power:1/4HP(250w)Customized size: AvailableApplication:Automatic roll filter is widely used to pre-filter of inductrial ventilation and air conditioner ventilation system. It's suitable for high dust capacity environment and the environments needs frequently change the filter material and constant air flow.Advantage:1.Using metal as he overall material,firm and reliable,meet the poorest working environments 2.Intelligent filter replacement system , effective energy conservation , reduce costs 3.Modular design to meet any type of system design and installation requirements 4.Low high-end options for different materials and configurations to meet the needs of different customers.There is a new material boxlocated on the top of the equipment.The initial pressure drop will increase when masses of high contcentration dirty air brought in,and when the initial pressure drip reches final pressure drop,the differential pressure switches opens,the switch will send signal to the control system,motor will work automatically,the dirty filter matrial will be wind onto the lower spool,at the same time clean filter material will take place of the dirty materialADVANTAGES* Using metal as he overall material,firm and reliable,meet the poorest working environments* Intelligent filter replacement system , effective energy conservation , reduce costs* Modular design to meet any type of system design and installation requirements* Low high-end options for different materials and configurations to meet the needs of different customers  Filter Height(mm) 1524182921342438274330483353365839624267Total widthRated air flow (m³/h)914920011300134001550017700198002190024000262002830012191270015000178002060023600264002920032000349003770015241587518750222502575029500330003550040000436254712518291905022500267003090035400396004380048000523505655021342222528250311503606041300462005110056000610756597524382540030000356004120047500528005840064000698007540027432857533750400504535053100594006570072000785258482530483315040000484505610063750714007906086700943501020003353364624400053295617107012578540889559537010378511220036583978048000681406732076500858809486010404011322012240039624309552000629857293082875928201027851127101228551326004267464105600067890786408925099960110670121380132090142800457249725612007267584150956251071101185751300501415251530004877530406528077520897601020001142401264501387201509601632005182563556763478913901541083751213801343851473901603951734005486596617162083642954431147501285201422901560601698301836005791629797558388187100749121125135660150195164730179265193800Q1.Are you a manufacture or trading company?A:We are a manufacure.Snyli Environmental Technology (Shandong) Co., Ltd was established in 2010, is a professional service provider of air purification products integrating R&D, production and sales, with registered brand- SYNLI.Q2: Where are air filters commonly used?A :HAVC(heating, air conditioning and ventilation systems) painting stations, chemical plants, pharmaceutical plants, cement or asphalt powder plants, clean rooms, power stations, heavy metal industries, gas turbines and cogeneration power plants, engineering and equipment plants, drying and baking rooms, hospitals, etc.Q3: What are your testing criteria?A: EN779:2012 ISO9001Q4: What is the international standard for air filters?A:Euro :Pre (G1-G4), Medium (F5-F9), HEPA (H10-H14) ULPA (U15-U17)American :Pre (MERV5-7), Medium (MERV8-14), HEPA (MERV15-19) ULPA(MERV 20)Q5: What is your sample policy?A: The sample price will be the product price of the standard order.
