The Hydro-Force Plus AS08P is the original injection sprayer concept at its most affordable: connect it to your machine's solution line and it automatically draws concentrate from the 5-quart container at a consistent dilution, so every job gets the same chemical load with zero measuring, mixing, or pumping. Carpet cleaners on industry forums call the Hydro-Force the difference-maker on large commercial work - and note it matters even more on portables, where strong prespray chemistry carries more of the load.
Use Cases
Where the Hydro-Force Plus earns its keep:
- Prespraying large commercial carpet areas quickly and evenly before extraction
- Portable extractor setups that lean on chemistry to offset lower machine performance
- Applying deodorizers and protectants with repeatable dilution
- Crews that want one sprayer permanently plumbed into the solution line instead of pump-ups
- Pre-treating up to 45 minutes ahead of the wand for better dwell and penetration
Consistency is the quiet advantage of an injection sprayer. With a pump-up, the mix depends on whoever filled it that morning and the pressure falls as the tank empties; the Hydro-Force draws concentrate at a fixed ratio from the first square foot to the last, so the chemistry on job ten matches job one. That repeatability is why supervisors put one on every truck: prespray cost per job becomes predictable, and callbacks from under-applied prespray drop. The transparent 5-quart container shows at a glance how much concentrate remains, and the long-lasting injection valve is field-serviceable. If you want adjustable ratios or a side-refill port, step up to the AS08 Pro - otherwise the Plus delivers the same gun, wand, and valve at the best price in the line.
Specifications
Operating pressure range 100 to 1,000 PSI. Blow molded 5-quart transparent container. Spray gun rated at 2,600 PSI and 7 GPM. 18-inch stainless steel wand. Chemically-resistant seals. Long-lasting injection valve. Seven dilution ratios available using metering tip kit NA0816A (sold separately). No side-refill port - see the AS08 Pro model if you need side refill.
Related parts: NA0816A metering tip kit; AS68A bottle with cap and tether; AS68L cap only; AS69A tether only; NA0868 Hydro-Force knob.
Setup takes about two minutes: tee the sprayer into the solution line, drop the draw tube into the concentrate container, and pull the trigger to prime.
Spare wear parts - bottles, caps, tethers, and the metering knob - are stocked individually, so the sprayer stays in service for years without replacing the whole unit.
Frequently Asked Questions
What is the difference between the AS08P Plus and the AS08 Pro?
The Plus uses the same durable spray gun, stainless extension, and injection valve as the Pro but at a lower price. The main trade-offs: the Plus has no side-refill port and a non-adjustable factory dilution unless you add the NA0816A metering tip kit.
What dilution ratio does it spray?
It is factory set to inject at roughly 1:8. Adding the NA0816A metering tip kit (sold separately) gives you seven selectable dilution ratios.
Will it work with my portable extractor?
Yes - it operates from 100 to 1,000 PSI, which covers portables and truckmounts alike. Forum users specifically recommend injection sprayers with portables because consistent prespray makes up for lower machine pressure.
How do I keep the injection valve working?
Check and rinse the inline filter monthly and prime the solution line before hooking it up. Sediment on the filter is the most common cause of inconsistent draw.
