Part 2: แผ่นกรองอากาศของคุณพร้อมสำหรับพายุใหญ่ในครั้งต่อไปรึยัง ?

ระบบกรองอากาศขาเข้าของกังหันก๊าซมีขั้นตอนในการกำจัดละอองฝน โดยทั่วไปจะมีขนาดมากกว่า 5-10 ไมครอน. แคมฟิลมีตัวกรองจำนวนมากที่มีคุณสมบัติป้องกันละอองน้ำและสารปนเปื้อนที่จะเข้าสู่เครื่องยนต์. รูปที่ 1 ตัวกรองขั้นสุดท้ายที่เหมาะสมแก่การป้องกันน้ำ

Graph 1 illustrates the results of a deluge test which measures filter pressure drop (dP) over time while the filters are continuously sprayed with water at 2500 CFM and 0.5 LPM² flowrate. Four filters were tested: Camfil’s 12” CamGT 4V-300 rated an F9 efficiency, Camfil’s 24" CamGT 3V-600 E11³, two 12" competitor F9 filters, and one 17" competitor F9 filter. Both CamGTs were superior in performance due to the features outlined in Figure 1, however, the media depth of the CamGT 3V-600 filter allowed it to maintain the lowest and most stable dP when challenged with high water volume, even with its higher efficiency. Further, neither CamGT leaked, whereas the rest showed signs of bypass in under four minutes.

The risk of bypass decreases when there are filter stages protecting the final filter, and for this reason, Camfil recommends a multistage static filtration system for wet and humid area. Inlet filter systems which have horizontal filter cartridges, or a "Cross Flow" configuration, however. have an extra challenge in that water can accumulate in the media pleats on top of the filters. In this case, water and contaminants could penetrate through standard media. If a cartridge filtration system already exists at your site, Camfil offers a robust design and hydrophobic media options that will prevent water penetration and keep the engine clean:
