- Top-mounted gauge
- Noisey pump action
- Cheap feel
Price as reviewed:
There’s quite a heavy, solid feel to the Air Tower 4.
It’s reasonably well built but still feels a little plasticky compared to many of the other more luxurious pumps in this test. The pumping action felt rough and made a noise not too dissimilar to sawing through wood.
This did ease a little with use, but not much. The small gauge is top-mounted and 100psi has an extra red increment mark. Along with the marker bevel it’s very easy to read, if not the most accurate.
The chuck doesn’t have an air bleed but it fits easily and seals well, though storage for the hose is pretty poor.
