새로운 Walkerfiltration의
Alpha Serie

Exceptional engineering. Improved performance.
Customer focus

18가지의 광범위한 필터모델과 4/1"~3"까지의 배관 접속구경의 제품을 제공하며 1,500SCFM(2,550Nm/h)까지의 유량을 제공합니다.

최적화된 하우징의 모듈디자인은 최적의 성능을 보장하며 설치의 편리성과 다기능의 커플링을 제공합니다.
워커의 EP코팅이 적용된 알루미늄합금 하우징은 견고하 며 부식을 방지하는 최고의 제품입니다.

성능과 효율의 극대화를 위한 맞춤형 디자인
오일제거에 탁월한 유리 섬유사 재질과 억류방지를 위한 특별한 디자인은 광범위한 오염방지와 원활한 배수를 보장합니다
특별한 재질의 소재구성은 압력의 저하를 최소화 하며 에너지 효울성을 향상시킵니다.
균형잡힌 중심축, 진동방지, 등급에 따른 엘레멘트 컬러, 방진효과
1/4"~3"의 나사식 하우징은 walker사의 EP 코팅 보호막으로 인하여 부식을 방지하는 알루미늄합금으로 제작되었습니다.
독창적인 앤드캡은 진동의 방지와 안정성의 향상 그리고 배수 의 도움을 위해 디자인되었습니다.
엘레멘트의 코드에 따른 색깔은 등급의 구별을 보다 쉽게 합니다.

technical notes

  • 1

    Direction of air flow is inside to out through the filter element.
  • 2

    Pop up indicator (65DPUG) are fitted to models 3022 toA3051 as standard. Differential pressure indicators (65DPIG) are fitted to models A3052 to A3303 as standard. AC grade filters do not include DP equipment.
  • 3

    Threaded filters are fitted with float operated automatic drain valves. ADV6000C on models A03011 to A3051 and ADV 6000 on models A3052 to A3303. Models A3052 to A3303 can be adapted to use ¼" drains with a reducer
  • 4

    Activated carbon filters must not operate in oil saturated condtions and will not remove certain types of gases including carbon monoxide (CO) and carbon dioxide (CO2).
  • 5

    Threaded filters are manufactured from cast aluminiun alloy and are PED 97/23/EC compliant for group 2 gases.
  • 6

    Threaded connections are Rp (BSP parallel) to ISO 7/1 or NPT to ANSI B2.1 if supoplied within NORTH America.
  • 7

    For NPT connections, add the suffix N e.g. A3011WSN
  • 8

    Filter elements should be changed every 12 months / 8000 hours (whichever comes first). Activated carbon filter elements should be changed every 6 months / 1000 hours(whichever comes first)
