Featuring a 3 cubic feet per minute airflow, a large sight glass for easy oil level and contamination monitoring, and a leak-proof blank-off valve for accurate vacuum readings, it’s engineered with a sloped housing and oversized fill port to streamline maintenance. Durable hoist points enable hands-free carrying with compatible straps, making it a top choice for HVAC professionals seeking reliability and speed. ## Description The hilmor Vacuum Pump makes oil changes easy with innovative design improvements like a sloped and channeled front housing that creates a natural drain flow, oversized fill port for pouring new oil quickly, and a gas ballast to prolong oil life. Two durable hoist points allow the pump to be transported hands-free using the hilmor HVAC/R Carrying Strap (sold separately). This reliable pump also features an oversized sight glass to identify oil level and detect contamination clearly and a blank-off valve to isolate the pump for accurate vacuum readings and easy oil change without losing a vacuum. Review: Solid Pump! - Nicely built pump with good quality feeling. Pulled down to 25 microns for my two-zone mini split system in an hour or so with 100LF of lineset. I was on the fence to go with a bigger pump based on some other reviews and info I read but I’m glad I chose the 3CFM pump and had no issues. I used a Appion hose with 3/8” and 1/4” fittings to a JB core removal tool with COS digi gauge. Review: Short term review - I was a little hesitant to get a 3cfm vacuum since all my tech buddies use 6 and up cfm. We'll I only work residential and today I Vacuumed a 5 ton system today in like 20 minutes with 1/4 in hoses I'm a fan of hilmore for sure ## Features - Makes oil changes fast and easy with a sloped and channeled housing and an oversized oil fill port - Two durable hoist points for hands-free carrying - Large sight glass for quickly identifying oil level and detecting contamination - Leak-proof blank-off valve isolates the pump from the system for accurate vacuum readings and easy oil change without losing a vacuum - Compatible with the hilmor HVAC/R Carrying Strap (sold separately) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NCOPH1N | | Air Flow Capacity | 3 Cubic Feet Per Minute | | Best Sellers Rank | #116,018 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #30 in Lab Vacuum Pumps | | Brand | Hilmor | | Brand Name | Hilmor | | Color | green | | Customer Reviews | 4.7 out of 5 stars 29 Reviews | | EU Spare Part Availability Duration | 5 Years | | Global Trade Identification Number | 00885363144659 | | Included Components | Vacuum Pump 3 CFM | | Item Type Name | hilmor Vacuum Pump 3 CFM, 1947970 | | Item Weight | 19.7 Pounds | | Manufacturer | Newell Brands | | Manufacturer Part Number | 1947970 | | Material | PE_ (Polyethylene) | | Material Type | PE_ (Polyethylene) | | Model Number | 1947970 | | Power Source | Corded Electric | | UPC | 885363144659 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Hilmor - **Color:** green - **Item Weight:** 19.7 Pounds - **Material:** PE_ (Polyethylene) - **Power Source:** Corded Electric ## Images ![hilmor Vacuum Pump 3 CFM, 1947970 - Image 1](https://m.media-amazon.com/images/I/71+udwH94RL.jpg) ![hilmor Vacuum Pump 3 CFM, 1947970 - Image 2](https://m.media-amazon.com/images/I/81fffvWYIkL.jpg) ![hilmor Vacuum Pump 3 CFM, 1947970 - Image 3](https://m.media-amazon.com/images/I/81F6ZfLrEUL.jpg) ![hilmor Vacuum Pump 3 CFM, 1947970 - Image 4](https://m.media-amazon.com/images/I/81yYM+9TFvL.jpg) ![hilmor Vacuum Pump 3 CFM, 1947970 - Image 5](https://m.media-amazon.com/images/I/81VWeE6GRML.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Is that two stage vacuum pump?** A: Yes, the 1948121 is Two Stage Rotary Vane. **Q: Can I use a 7 cfm vacuum pump on a car?** A: That's plenty for a car system...you can also use a smaller, less expensive 1 or 2cfm pump. 5 cfm and larger are for residential and commercial A/C systems. **Q: What's ultimate vacuum this 12 cfm vacuum pump can pull in microns?** A: I walked away from it long enough to see it hit 293. **Q: Can i use the 5 or 9 cfm on my freeze dryer? i need at least 150 or better mtorrs. and is it maintenance free or do i have to cange the mineral oil?** A: Oil needs to be changed occasionally when it becomes cloudy or discolored for better vacuum. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid Pump! *by C***N on November 8, 2024* Nicely built pump with good quality feeling.
