Suction Filter FAQ Guide
As an essential filter, the primary purpose of Filson suction filter is to remove and capture impurities.
The main function of suction strainer is to:
- Capture and collect large contaminants in most gases or liquids
- Reducing the entry of unwanted particles
- Protect downstream equipment from damage and prolong its lifespan
- Maintain clarity of filtered liquids or gases
- Improve the whole filtration efficiency
Filson suction filter is mainly designed to capture impurities and prevent particles from entering the pump. The general micron rating is between 1 and 250 micron, typically 25 to 150 micron.
Besides, if you choose Filson medical suction filter, the filtration accuracy can be smaller down to 0.3 micron.
As we all know, strainer with customized sizes is suitable for most pump, and its purpose is to capture both large and small particles from liquids before it flows into the key filtration parts.
For this reason, using a suction strainer before a pump can largely prevent particles entering pump, keep filtration pipe clean and keep the whole filtration process smoothly.
To guarantee long service time and continuous good performance, you should clean your hydraulic suction filter regularly. There are two common cleaning methods:
- Chemical solvent cleaning method: place hydraulic suction filter in a solvent tank and rinse filter using solvent. While rinsing, use small brush to remove left dirt and debris. The solvent can dissolve oil, so rinse filter totally using solvent. Next, after cleaning, take filter out solvent and make it dry through shaking off excess solvent.
- Ultrasonic cleaning method: put suction filter in cleaning agent for approx. 15 minutes and remove dirt using a brush. Then, flush with fresh cleaning fluid from the inside to the outside. Next, blow out with compressed air from the inside to the outside.
Filson suction filter in HPLC contains activated carbon, and can be used to trap and remove contaminants in the mobile phase. Besides, HPLC suction filter is easy to install and replace.
The main features of suction filter in HPLC as following:
- Capture contaminants from the mobile phase: With highly purity activated carbon, suction filter has better permeability to trap particles in the mobile phase. And it can largely minimize chromatographic interferences resulting from contaminants.
- No effect on gradient delay: Being installed in front of pump, HPLC suction filter can not make effect on gradient delay.
- Fit LC/MS applications: Due to its low bleed, suction filter is suitable for LC/MS applications and remove contaminants from them.
