The California Air Tools 20040DSPCAD Ultra Quiet and Oil-Free Air Compressor with Air Drying System and Auto Drain in a Soundproof Cabinet is designed to be one of the quietest 4.0 horse power air compressors in the industry having only 65 decibels of sound. The two powerful 2.0 HP motors operates at only 1680 RPM creating less noise, vibration and wear.


The oil-free dual piston pump system is engineered for longevity, high performance and durability. The SP-Motor/Pumps are tested for a minimum pump life of over 3000 hours before service. The sturdy steel soundproof cabinet has a large 20-gallon steel air tank and caster wheels that makes it easy to move. The interior of the cabinet is lined with acoustic sound proofing foam insulation to reduce the air compressor's noise and vibration. The two latching door handles allow for easy access to the air compressor. The four exhaust fans are designed to remove the air from the cabinet for a cooler running air compressor.


The Air Dryer is specially designed to remove the water vapor from the air to protect sensitive tools and machinery. To dry the air from the air compressor, an aftercooler and dryer are utilized. The aftercooler is a heat exchanger for cooling the discharge air from the air compressor. The water vapor from the compressed air is condensed into liquid form and pushed into the Air Dryer.


The factory installed California Air Tools EZ-1 Automatic Drain Valve has been designed to eliminate manually draining your air compressor air tank. The manually set timer allows you to set the time for both the frequency and duration of the draining process. This air compressor is ideal for anyone working inside (office, shop, store, warehouse or home) where noise is a major issue.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.
