Based on suggestion by BHPian Sommos, started looking at VIAIR 87P, and this turned out to be very reliable and powerful, just that it doesn't have auto stop etc features, also an analogue pressure guage. Not sure if I can fill bicycle tyres etc with this. But this comes as strongly recommended and sells in matured markets like US. When I called up SwastikFab they recommeded going for 88P as its more powerful and fills air quickly. The only negative point about VIAIR is high price. But, the person on call was super confident saying this is a lifetime product and he hasn't done a single replacement till date. Probably this will last much longer and hence cover up the price of 2 such inflators which I may end up buying in the same time period. I am strongly considering 87P/88P - how long does it take for 87P to fill a tyre from 20 psi to 33 psi ? |
I have been using VIAIR 90P for last 3 months, after my previous GoMechanic inflator, which was gifted by someone, stopped working after just 3 uses. 90P is extremely fast, does not sound strained even a little bit even when filling the whole tyre. I use it with my cars and bicycles.
I evaluated 87P, 88P and 90P before my purchase - the feedback that I got from friends in US was that there is not much difference in the fill rates, 88P being the is the most powerful of the lot. 235/55/R18 tyres of my Kodiaq fill up from empty to 35PSI in under 3 minutes with 90P. (Another 30-40 seconds would not really matter much anyway). Also, I got consistent personal feedback that these long-lasting products, and do not go bad easily. I would suggest 88P over 87P since 88P is rated at 120PSI - a product rated for higher pressures would be more resistant to wear and overheating. Also, rated pressures for road and hybrid bicycle tyres often go above 60PSI and that would be important if you want to use the inflator with such tyres. 88P also comes with Presta adapter (not a big deal - Schrader to Presta adapters are cheap).
I was looking for 88P, but got 90P since 88P was not in stock at that time. I guess the only thing that 88P does not have that is in 90P is a bleeder valve on the tyre connector - the valve makes it easier to adjust pressure accurately. |
