When you're shopping for separation equipment, the choices can feel scattered. Do you need to separate nitrogen from compressed air for a draught beer system, or do you need to separate metal debris from your garage floor? These two products address completely different separation jobs, yet both fall under the filtration separation umbrella. Here's a head-to-head look at the Green Air nitrogen membrane separator and the ASR Outdoor magnetic pickup tool two-pack, so you can see which one matches your workspace.
Quick Verdict
If you operate a commercial beverage system or industrial process that needs a steady supply of nitrogen, the Green Air membrane separator is the high-capacity solution. If you're a garage or workshop owner who wants a quick, easy way to pick up stray metal, the ASR Outdoor magnetic pickup tool pair is the practical buy.
At a Glance
| Product | Price | Condition | Separation Job | Price Indicator |
|---|---|---|---|---|
| Green Air Nitrogen Membrane Separator | USD 1,500.00 | Used | Produces nitrogen for draught beer or industrial/beverage systems | |
| ASR Outdoor 2-Pack Magnetic Pickup Tool | USD 24.42 | New | Picks up and releases magnetic metal debris |
Where Each Product Wins
The Green Air membrane separator wins for operations that need large-scale nitrogen generation. It's built for high-demand draught beer lines, beverage processors, or industrial gas applications, with a 200 PSI rating that suggests serious throughput capability. The ASR Outdoor magnetic pickup tool wins for portability and simplicity. Its two compact tools quickly sort magnetic metal from other material, and the rubberized quick-release handle makes dumping the load easy.
Product Notes
Green Air Nitrogen Membrane Separator

Choose this if your business depends on a steady nitrogen supply for draught beer, beverage processing, or an industrial gas application. The membrane is 45 inches long, about 6-8 inches wide, and weighs roughly 30 lbs. It carries a 200 PSI rating. One limitation to keep in mind: this is a used unit, and it's specifically the nitrogen membrane only-the compatible Green Air compressor is not included. It was pulled from a draught beer location that closed, so you're buying a component that needs to be integrated into an existing compressed-air setup. If you're planning a from-scratch nitrogen system, factor in the additional equipment needed to make it operational.
ASR Outdoor 2-Pack Magnetic Pickup Tool

The ASR Outdoor magnetic pickup tool set is the quick, portable answer to separating magnetic debris from non-magnetic material. For $24.42, you get two handheld tools that each grab up to 8 lbs of metal, with a rubberized quick-release handle that drops the load with a squeeze. Just under five inches tall, they're compact enough for a garage or workshop drawer. The main limitation is the scope of what it can do: it only attracts magnetic materials, so it won't help with nitrogen generation, liquid separation, or finer filtration work. It's also a manual tool-there's no motor or automated process. Think of it as a cleanup and sorting aid for found gold, stray nails, metal shavings, and other magnetic debris, rather than a multi-function separation machine.
Final Choice by Use Case
If you need to produce nitrogen for a commercial draught beer system or industrial process, the Green Air membrane separator is the practical choice despite the higher price and used condition. If you need a portable, handy magnetic separator for shop cleanup, metal recovery, or sorting, the ASR Outdoor two-pack is the way to go. These two tools don't overlap in function, so your decision really comes down to the type of separation you're doing.
