Viair

Viair 88P Portable Automatic Tyre Inflator Compressor

Specification	DEWALT 20V MAX Cordless Car Vacuum Cleaner Bare Tool	Viair 88P Portable Automatic Tyre Inflator Compressor
Price	₹9,999	₹8,990
Weight	1.8 kg without battery	3.9 kg
Warranty	1 Year Official Brand Warranty	1 Year Official Brand Warranty
Auto shut-off	not published	Preset pressure, so it stops on its own
Bare tool	The DCV517B suffix means tool only. A 20V MAX battery and charger together cost a significant fraction of the tool price again	not published
Duty cycle	not published	Roughly 25 minutes on at 30 PSI, then a cooling period. This is the specification that decides whether a compressor survives, and it is in the manual if anywhere
Filter	Washable, and it must be genuinely dry before reuse	not published
Flow rate	not published	1.47 CFM
Maximum pressure	not published	120 PSI
Not for	not published	Truck or large SUV tyres from flat -- the 400P is the model for that
Power	not published	Direct to the battery with alligator clips, not a cigarette lighter socket -- a socket cannot supply the current
Runtime	About 18 minutes on a 5.0 Ah battery	not published
Suction	Strong for a handheld, but a 0.5 litre tank empties fast	not published
Voltage	Battery tool, so mains voltage is only a question for the charger, which is dual voltage	not published
Wet and dry	Yes, up to about 0.5 litres of liquid	not published
Why it matters	not published	Inflating four tyres from flat can exceed the duty cycle in one session. Let it cool between tyres
Why sold this way	It assumes you already own DeWalt 20V MAX batteries from other tools. If you do not, budget accordingly	not published
