Stanley Bostitch CAP1512-OF

 Trim Air Compressor


It’s one of the “little things” in life!


Sometimes it’s the “little things” in life that can end up making a world of difference, case in point, the Stanley Bostitch’s Trim Air compressor. It’s packed with a lot of “little things” that make this compressor a pleasure to use.

First and foremost is the size of this compressor, it’s compact. It weighs a mere 23 1/2lbs and measures 13 1/2″ tall, 17″ wide and 12 1/2″ deep, extremely portable. It stores almost anywhere, is well balanced and it’s a breeze to carry from one jobsite to another to do small trim jobs. But don’t let its size fool you, its high output oil- free pump produces 2.8 CFM @ 90PSI and has 150PSI maximum operating pressure for using up to two finish nail guns at a time. Powered by a 1.5HP 12amp motor, this compressor plugs in just about anywhere and drawing only 12amps, it’s not likely to trip a breaker or blow a fuse.

Looking at the dashboard of this compressor you soon realize that everything you need is right up front. No need to fumble around trying to find the on/off switch, pressure regulator, hose connection or the pressure gauges, they are all up front and easily accessible. The tank pressure gauge and outlet pressure gauge are a full 1 1/2″ in diameter, easy to read and are protected by the dashboard which forms a shroud around them.  I’ve broken off or damaged several compressors gauges over the years on other compressors because they haven’t been neatly tucked away like these ones are. The outlet pressure is easily controlled by a large red knob that sits between the two gauges, turn it clockwise to increase the outlet pressure and counter clockwise to decrease the outlet pressure.

The on/off switch has a clear soft rubber protective cover over it that keeps dust and debris out of the switch. This switch is also illuminated and glows red indicating when the compressor is on, preventing gun misfires from shooting nails when the compressor is off and low on air.









Looking at the left side and rear of the compressor there are three appreciated features. A handy integrated cord storage that keeps the 6′ power cord stored and out of the way when not in use. The molded plastic back features a storage pocket for tools, fasteners or other necessities and a Velcro strap attached to the back of the compressor that can be used to store a nail gun, air hose or other tools.

A quick glance at the front of the compressor and you see what looks like two “handles” facing the operator and I suppose you could use them for just that but that’s not their main function. These two “handles” form the roll cage of the compressor. Simply put, knock the compressor over (which is difficult because of its low center of gravity) and this roll cage protects the dashboard and its valueables against damage. Nice feature considering the abuse that compressors usually take, in the back of a truck or on a jobsite.

This compressor has other features that you may not think about but are much appreciated when you realize that you’ve got them. Features like, a low center of gravity, almost 2″ diameter non-marring soft rubber feet that grip well to most surfaces,  a ball type drain valve that easily drains the air tank and a quite running compressor that won’t give you a headache working next to it, round out the features of this compressor.

One thing that a perspective purchaser needs to consider when purchasing any compressor is, what will that compressor be used for? Keep in mind that this compressor’s tank is 1.2 gallons and has been designed and built for trim work. Its smaller tank size simply means that it will cycle more often than a compressor that has a much larger tank with more reserve air. With that in mind, I ran a series of tests with three different size nail guns. The guns I used in this test were 23 gauge with 1 3/8″ nails, 18 gauge with 2″ nails and a 16 gauge gun with 2″ nails. I attached the nail guns to the compressor with a 1/4″ ID hose that was 50′ long and the outlet pressure was set at 100PSI. The material I chose for this test was 3″ thick hard maple.




(putting the compressor through its paces and working flawlessly)

I was curious to see how many nails of each of the three sizes I could shoot before the compressor kicked on and how long it took for the compressor to re-supply the tank with enough air to continue nailing. I shot on average; 23 of the 23 gauge nails, 13 of the 18 gauge nails and 10 of the 16 gauge nails before the compressor kicked on. The compressor recovery time was only 14 seconds throughout the test. A quick recovery time from a quiet compressor was easy to take. Incidentally, with a completely empty tank and an attached 50′ air hose, this compressor takes a mere 45 seconds to fill.



If you’re in the market for a small compressor that’s packed with well appreciated little features, you owe it to yourself to consider the Stanley Bostitch Trim Air. Sometimes it’s the little things that can end up making a world of difference.
