Numax SFR2190 21 Degree Framing Nailer

If you’re interested in construction, home renovation, or just some advanced DIY, I’m sure you’ve heard of the Numax SFR2190. This has been the talk of the town for quite a while now, because of its wide array of unique features.

There’s no denying that Numax is a well-known brand, popular for its quality products. However, how true are their claims for this much-hyped nail gun?

Well, I’ve purchased this tool and have been using it for a while now. And let me tell you –I’m not disappointed. But if you’re wavering on the purchase and want to take an informed decision, that is completely understandable.

So, here’s an honest Numax SFR2190 review based on my very own experience.

Numax SFR2190 Framing Nailer

If you’re looking for a lightweight nail gun, the air-powered Numax SFR2190 is worth considering. With a durable magnesium body, this tool will help you tackle all sorts of framing projects.

The Numax SFR2190 has been designed, keeping both professionals and DIY-ers in mind. A plus point is that it’s really easy to manage. In fact, you can use it for long periods of time without feeling like your arms are going to fall off.

The product comes with a pre-assembled single fire trigger, which improves accuracy. You also have the option to use the red bump fire trigger for faster and uninterrupted nail discharge.


360 Degree Adjustable Air Exhaust

One of the most annoying things when using an air-powered nailer is all the dust that lands on your face. But with this particular nail gun, you can finally breathe in peace while working.

This innovative tool has a 360-degree rotating air exhaust that you can adjust. This allows you to keep the vent as far away from your face as you want. What’s more, you can even use it to clean up your workspace.

Compatibility with 21 Degree Plastic Collated Nails

The Numax SFR2190 framing nailer is compatible with any of the plastic nails within the 20-22 degree range. However, it is known to perform best with 21-degree nails.

Why is this an advantage? Well, plastic collated nails are easily available and quite affordable too. Also, you don’t have to worry about the dangers of a metal strip popping out or any glue-related messes.

Depth Adjustment

Another cool feature of the tool is that you have full control over the firing depth. This allows you to maintain consistency and make sure your nails are securely attached.

Nail depth will vary depending on the type of job. And since you can adjust these settings here, the tool brings quite a lot of versatility to the table.


  • Secure and comfortable handle
  • Easy to clean with built-in air filter
  • Anti-dry fire that detects low nail count
  • No mar-tip that prevents dents
  • No-slip teeth for better wood grip
  • Preinstalled widely compatible ¼” NPT fitting
  • Easy to load nails
  • There is no jam removal mechanism
  • Might leak air if not handled or stored properly

Frequently Asked Questions

  1. What is the tank capacity for this nail gun?

The minimum tank capacity for optimum performance is 3 gallons.

  1. What is the nailer’s working pressure?

The working pressure is within the range of 75-115 PSI.

  1. What kind of air compressor is best suited for this framing nailer?

The air compressor totally depends on what you’re using the nailer for. Typically, a pancake or small compressor would work fine for normal, intermittent nailing. But if you’re looking for faster, consecutive nailing, you’ll need something more powerful.

  1. What type of nails does the tool use?

The Numax SFR2190 uses round head nails that are 2 3/8 x .113 inches. While the tool works with 22-degree nails too, it performs the best with 21-degree nails.

  1. What air hose size do you recommend?

A ¼” or 3/8” air hose would work best.

  1. Do the nails always have to be plastic coated?

The nails don’t necessarily have to be plastic coated. But the strip holding the nails should be plastic.

  1. How well does this nailer work for corners, based on the width of its head?

The tip of the nailer is an inch wide. Nailing straight into a corner might be an issue, but it works fine if you angle it instead.
