"I used my new 400P EF for first time today and i was very impressed. I aired all four tires in short time on a Silverado. The tires are LT305/70R15's. The rear tires took me about 5 minutes each to top off at 35 psi. The front tires took me about 10 minutes each to top off. I am very happy with the 400P EF. The quality is top of the line. I highly recommend this portable air compressor."
"HEAVY DUTY METAL BODY/FAST"
"Works as promised. Allows me to air up tires and air bags remotely when hooking up to my trailer. Much quieter than other compressors I’ve used."
"Order was received quickly. Well packaged. Tested as soon as pump arrived. Only reason I give 4 stars vice 5 stars is calibration of the gauge on the air hose. Was off by a significant amount of PSI. Used two other external gauges to verify. However, pump is extremely fast, very quiet, and easy to use."
"Ordered a 400p late on Friday and showed up at my door on Saturday! High quality unit. Aired my tires up in a jiffy! Would recommend to anyone looking for a solid air compressor."
"I also have the 300P the new 400P is much faster and longer duty cycle very happy with the new unit"
"Excellent quiet air pump. I got to tell you the best part, to me anyway, of this pump, is the ability to connect the power line to the VIAIR 7-Way Power Access, 7-Way Blade to 2-Pin SAE 12V Power Source. It makes so much sense. I use it on my wife’s Ford Explorer, and the truck and trailer. It is so easy to use I fill the bike tires with it too. Great idea ViAir!"
"I have been using the 88P for four years. I was very satisfied with the 88P pump. I felt it took too long to inflate four 35-inch tires. I purchased the 400P LF with its new technology and am very satisfied with it. I tried inflating from 5 psi. The 88P was able to inflate to 30 psi in 4 minutes. The 400PLF was able to inflate to 42 psi in 4 minutes. I felt that this was sufficient capacity since I don't usually lower it to 5 psi. There was no compromise in the construction of the bag, and I am satisfied with the bag that was made specifically for this purpose."
"We chose this compressor to fill our RV 80 lb tires and it worked. I was surprised how efficient and QUIET it was. Impressive! We only hope it is as reliable when we need it."
