Single-stage High-Pressure Blower
Leynow · Single-stage Vortex Technology
Workstations require both negative pressure adsorption and positive pressure blowing simultaneously. Purchasing two blowers separately increases procurement costs and occupies equipment installation space.
Ordinary air sources output airflow with oil mist, contaminating processed workpieces and conveyed materials, affecting finished product quality and subsequent processes.
Looking only at power without considering the flow curve, the actual air volume cannot meet process requirements, resulting in incomplete blow-drying and uneven aeration.
Troublesome procurement of filters, pressure relief valves, and silencers; the complete machine is relatively large and difficult to embed inside automated complete equipment.
The same single-stage vortex air pump can perform negative pressure suction for adsorption and material suction, and also positive pressure high-pressure blowing for blow-drying and aeration; one machine covers two processes, reducing procurement and space occupation.
No mechanical contact between the impeller and pump chamber, no lubricating oil required in the pump chamber, clean output airflow, suitable for occasions with air source cleanliness requirements such as food, printing, and electronics.
Single-stage structure features large air volume and continuous airflow, suitable for flow-oriented working conditions such as aeration and oxygenation, blow-drying and water removal, and ordinary vacuum adsorption, with stable operation and fast response.
IP54 protected, Class F insulated motor, optimized heat dissipation duct; complete machine dynamic balance calibration, supporting long-term continuous operation under conditions of good ventilation and heat dissipation and matched working conditions.
Horizontal base design, compact body, can be directly embedded into automation equipment cabinets or inside complete machines, serving as a built-in negative/positive pressure air source unit.
Original factory accessories such as intake filters, pressure relief valves, and silencers can be supplied as a set; selection calculation based on air volume, pressure, and pipeline resistance, with troubleshooting and factory repair and maintenance provided.

Leynow single-stage high-pressure blowers (vortex air pumps / side channel blowers) have impellers with numerous blades. When the impeller rotates at high speed, gas enters the annular side chamber under the action of centrifugal force, circulates and pressurizes between the blades and the side chamber, and is discharged from the outlet.
Single-stage means one-stage impeller boosting, with a simple structure, large air volume, and continuous airflow; the air inlet forms negative pressure suction, and the air outlet forms positive pressure blowing, so one machine has both suction and blowing functions.
The impeller operates without contact with the pump chamber, no lubricating oil is required in the pump chamber, and the output airflow is clean; the complete machine has a simple structure and low daily maintenance, suitable for continuous operation of industrial equipment.
Compiled technical reference materials related to vacuum pumps for selection, equipment commissioning, and troubleshooting.
Air supply aeration and oxygenation for fish ponds and shrimp ponds, increasing dissolved oxygen in water.
Vacuum adsorption clamping of panels, suction collection of sawdust and dust.
Printing paper adsorption and conveying, bag opening blowing at packaging stations.
Material blow-drying and water removal, vacuum adsorption, guaranteed clean air source.
Negative pressure feeding, suction, and conveying of plastic pellets and powders.
Embedded in complete equipment as a built-in negative/positive pressure air source unit.
Continuous air supply aeration for fish ponds and shrimp ponds, improving dissolved oxygen in water.
High-pressure air knife blow-drying after workpiece cleaning, replacing manual wiping.
Automatic negative pressure feeding and conveying of plastic pellets and powders.
Negative pressure suction and collection of dust and debris, improving workshop environment.
Biochemical tank aeration and stirring, assisting sewage oxygenation treatment.
Embedded inside complete equipment to provide negative and positive pressure air sources.
Usage Limitations: Not suitable for extracting large amounts of dust, highly corrosive gases, or high-temperature gases; please install an intake filter at the front end for dusty working conditions; it is strictly prohibited to operate with the inlet or outlet blocked, otherwise it will cause internal overheating and damage the motor.
Selection Recommendations: For aeration, blow-drying, and ordinary adsorption, prioritize single-stage models; if there are many pipeline elbows and system resistance is relatively high, consider double-stage; for long pipelines and high resistance negative pressure working conditions, consider 4HB three-stage. Please include pipeline resistance in the calculation during selection, and it is recommended to reserve a 10-20% performance margin.
Single-stage has a one-stage impeller, characterized by large air volume and continuous airflow, suitable for flow-oriented working conditions such as aeration and oxygenation, blow-drying and water removal, and ordinary vacuum adsorption; double-stage has two-stage impellers with higher pressure difference, suitable for feeding working conditions with many pipeline elbows, relatively high system resistance, or requiring higher negative pressure; the three-stage 4HB series has even higher pressure difference, used for long pipeline and high resistance negative pressure processes. Please include pipeline resistance in the calculation during selection, and it is recommended to reserve a 10-20% margin.
Yes, the blower has independent air inlet and outlet ports, and can simultaneously perform negative pressure adsorption and positive pressure blowing; note that the inlet and outlet ports must not be directly short-circuited, otherwise it will cause overload and internal overheating.
Power cannot be judged alone; it must be comprehensively judged based on the required air volume, pressure, pipeline length, and number of elbows. Small-area workstation blow-drying and small fish pond aeration can consider 0.4-0.75Kw; assembly line blow-drying, medium-sized pool aeration, and panel adsorption mostly choose 1.5-2.2Kw. Tell us the working condition parameters, and we can assist in matching the model.
Leynow 2HB single-stage industrial models support long-term continuous operation under conditions of good ventilation and heat dissipation, matched working conditions, and unblocked inlet and outlet ports. For dusty working conditions, be sure to install a front-end intake filter and clean the filter element regularly to protect the impeller and motor.
Common accessories include: intake filter (essential for dust prevention), pressure relief valve (overload protection), silencer (reducing operating noise); Leynow can supply the complete set, and can also provide adapter suggestions according to on-site interface dimensions.
Yes. Accessories such as filters, pressure relief valves, and silencers can be supplied separately; we also provide technical consultation, troubleshooting guidance, and factory repair and maintenance services to help equipment resume production as soon as possible.
