I was going to go pick up this pump today but it's only rated to 75 microns, do I need one closer to 25 microns ? https://www.acklandsgrainger.com/AGIPortalWeb/WebSource/ProductDisplay/globalProductDetailDisplay.do?item_code=WWG4LTW8. I also kept looking and found this pump that has a 15 micron rating, just looking for opinions. https://www.acklandsgrainger.com/AGIPortalWeb/WebSource/ProductDisplay/globalProductDetailDisplay.do?item_code=WWG4LTW7 Sent from my iPhone using Grasscity Forum
