How each drive makes pressure
A hydraulic press multiplies force through an incompressible fluid. In a manual hydraulic like the FLUID, the operator pumps a ram; the pressure curve is literally in your hands. You feel the material give, and an experienced operator steers the press by that feel. There is no compressor, no air line, and almost nothing to wear out.
A pneumatic press makes force from compressed air through a cylinder. In the AIR, a regulator sets the force and the cylinder repeats it identically, press after press, hour after hour. The operator's job becomes loading, timing, and collecting, not pumping. That repeatability is what a production shift is built on.
The trade-offs that actually matter
| Manual hydraulic | Pneumatic | |
|---|---|---|
| Force delivery | Operator-pumped; pressure steered by feel | Regulator-set; identical every cycle |
| Duty cycle | Boutique batches, R&D, process development | Continuous commercial production |
| Infrastructure | A bench and an outlet | Shop air (90–120 PSI) plus an outlet |
| Operator load | Physical: every press is a pump stroke | Low: load, press a button, collect |
| Entry cost | Lowest cost of entry into real tonnage | Higher, amortized across throughput |
Match the drive to the batch
Choose hydraulic when your batches are small and your parameters are still moving. R&D, cultivar trials, recipe development, boutique SKUs: anywhere the operator's judgment is part of the process. The 20-ton FLUID covers this range without asking for an air line.
Choose pneumatic when the recipe is settled and the bottleneck is labor. If you know the temperature, the dwell, and the pressure curve, the machine should run them, not a person's arm. The 8-ton AIR runs that shift, and the 100-ton KWÄD carries it to industrial scale.
Either way, force is only half the equation. Temperature and dwell set what the force extracts, and the bag you load has to match the platen you choose.
