HIGH PRESSURE SERIES · YEBL-HP
Past one bar. Still oil-free.
The YEBL-HP series is regeneration taken to the deep end — multi-stage side-channel blowers that reach 1040 mbar of pressure and -730 mbar of vacuum on a 10 HP frame, where ordinary ring blowers run out of lift. Five trims, 2 to 10 HP, all oil-free.

01Positioning
Where the High Pressure Series sits
The side-channel family is a pressure ladder. Knowing which rung your duty needs stops you over-buying a triple-stage machine for a single-stage job — or under-buying and stalling.
up to ~460 mbar / -340 mbar
Flow-led general duty — aeration, light vacuum, conveying.
pressure reach
up to 660 mbar / -440 mbar
Deep-tank aeration and higher-lift vacuum at moderate flow.
pressure reach
up to 1040 mbar / -730 mbar
The deep end — multi-stage pressure and vacuum, still oil-free.

02Working Principle
Stacking stages to cross one bar
The High Pressure Series works on the same regenerative principle as every ring blower — a vaned impeller throwing air into a side channel and scooping it back, adding a pressure step on every pass. The difference is how many times that whole sequence is repeated in series. The DS trims put two full stages back to back; the TS flagship adds a third. Each stage begins regenerating from the raised pressure the previous stage handed it, so the increments compound rather than average.
Compounding is what lets a purely aerodynamic, contact-free machine climb past atmospheric pressure differential — 1040 mbar is more than a full bar of lift with no piston, no lobe and no lubrication. Run the same machine from its suction port and the stages compound in the other direction to pull -730 mbar of vacuum. It is the deepest duty the side-channel architecture reaches while staying oil-free.
The trade-offs are honest: more stages mean more length, more weight per HP, more heat in the air and a stricter demand on the relief valve. But for clean-air high-pressure or high-vacuum work that must stay contamination-free, no other compact machine matches it.
03Match the trim to the duty
Choosing within the series
Inside the YEBL-HP range the choice is set by the pressure or vacuum figure you must actually hold, and airflow follows. The YEBL-HP-DS-47 opens the range at 650 mbar on a compact 2 HP frame for small, deep-pressure jobs where flow is a trickle. Step up through the DS trims and both pressure and flow grow together — the YEBL-HP-DS-120 holds 820 mbar at 120 m³/hr for mid-band deep aeration and vacuum.
When the duty crosses into genuine over-one-bar territory — or needs the -730 mbar vacuum no double stage reaches — the triple-stage YEBL-HP-TS-175 is the answer, and it is the only trim in the family that gets you there. Do not over-specify it for a job a DS trim covers: the third stage adds weight, heat and cost you only want when the duty truly demands the reach.
Match the trim to the duty
- 650–750 mbar, low flow: YEBL-HP-DS-47 / DS-87.
- 740–820 mbar, mid flow: YEBL-HP-DS-120 / DS-165.
- Up to 1040 mbar or -730 mbar: YEBL-HP-TS-175 only.
- Still under 660 mbar? A double-stage YEBL-DS is cheaper.

05Construction & Materials
Engineered for the load a full bar imposes
Multi-stage housing
Two or three aligned side channels in a rigid casing, ported so each stage feeds the next with minimal inter-stage loss. Heavier per HP than a standard side-channel because the sustained pressure load demands it — weight runs 28 kg to 86 kg across the five trims.
Impellers & shaft
Two or three balanced aluminium impellers on one motor shaft — no coupling, no gearbox. Tight, precise clearances hold the pressure; the impellers are the only wearing surfaces and are serviceable as spares from the YEBL-IMP range.
Protection is mandatory
At 1040 mbar a relief valve and inlet filter are not accessories — they are required. Supplied with the unit. Give the motor fan cowl clear cooling air; multi-stage air runs hot, and a dead-headed high-pressure blower overheats fast.
06Install & Maintain
Commissioning & Care
Install on a rigid level base, confirm rotation against the housing arrow, fit flexible connectors to isolate pipe strain, and never let the machine run against a fully closed valve. Log baseline current at commissioning — a rising amp reading at the deep end is the earliest warning of a clogged filter or restricted line.
07Applications
Duties that demand the deep end
- Deep vacuum lifting — Holding and lifting heavy or porous loads where -730 mbar is needed on an oil-free machine — CNC hold-down of thick stock, deep-draw forming.
- High-pressure aeration — Very deep tanks and high-backpressure diffuser grids that need 700–1040 mbar continuously.
- Gas boosting & leak test — Clean-air pressure boosting and leak-testing where oil contamination would invalidate the result.
- Dense conveying & degassing — Higher-pressure conveying and vacuum degassing in food, pharma and plastics that ordinary side-channel blowers cannot reach.
