Common Challenges in Industrial Air Source Working Conditions

Difficult to balance dual pressures in processes, oil contamination damages materials, large air volume loss, limited matching and difficult integration.

Need Both Negative Pressure Adsorption and Positive Pressure Blowing

Processes require both negative pressure adsorption and positive pressure blowing simultaneously. Purchasing two blowers results in high procurement costs and occupies equipment installation space.

Air Source Contains Oil, Contaminating Workpieces and Materials

Blower output airflow carries oil mist, contaminating processed workpieces and conveyed materials, causing a decline in finished product quality.

Insufficient Pressure and Air Volume, High Pipeline Resistance Loss

Selection failed to consider pipeline elbow resistance, actual blower output cannot meet process requirements, resulting in poor production results.

Incomplete Accessories Matching, Limited Equipment Integration and Installation

Difficult procurement of matching filters and pressure relief valves; traditional blowers are large in size and cannot be embedded in automated complete equipment.

Leynow High-Pressure Blower / Vortex Blower Working Principle

  • The Leynow vortex high-pressure blower (side channel blower) features an impeller with numerous blades. As the impeller rotates at high speed, gas enters the annular side cavity under centrifugal force and is repeatedly circulated and pressurized between the blades and the side cavity.

  • Single-stage, double-stage, and three-stage represent the number of impeller pressurization stages; the higher the number of stages, the greater the achievable pressure difference. After pressurization is completed, the gas is discharged from the outlet; the inlet achieves negative pressure suction, and the outlet achieves positive pressure blowing.

  • The impeller operates with non-contact and oil-free rotation, outputting clean air; the overall structure is simple, with low maintenance requirements, making it suitable for continuous operation of industrial equipment.

Technical Information & Materials

Project Selection Reference Suggestions
  • Confirm core indicators: required ultimate vacuum, actual pumping volume;
  • Clarify the extracted medium: water vapor, dust, corrosive gases, etc., to determine whether filtration, condensation, or explosion-proofing is needed;
  • Confirm the usage environment: indoor/outdoor, on ships, high temperature and humidity, dust environment;
  • Usage mode: intermittent use or long-term continuous operation;
  • Standalone equipment or a complete central vacuum station.

Usage Restrictions: Not suitable for extracting large amounts of dust, highly corrosive, or high-temperature gases; an inlet filter must be installed at the front end for dust conditions; it is strictly forbidden to operate with the air inlet and outlet completely closed, as this will cause overheating and burn the motor.

Selection Recommendations: For aeration and blow drying, prioritize single-stage; for pipelines with many elbows and high resistance, choose double-stage; for long pipelines with high resistance and negative pressure conditions, choose the 4HB three-stage; please calculate pipeline resistance during selection, and it is recommended to reserve a 10-20% performance margin.

Customer FAQs

Focusing on selection configuration, installation and commissioning, and after-sales questions, providing you with professional and efficient answers.

How to choose single-stage, double-stage, or three-stage high-pressure blowers?

Prioritize single-stage: for aeration, blow-drying, and ordinary adsorption, pursuing large flow; double-stage: for requiring higher negative pressure, many pipeline elbows, and high resistance; three-stage 4HB series: for ultra-high pressure difference, long pipelines, and high resistance negative pressure working conditions; pipeline resistance needs to be included in the calculation during selection, and it is recommended to reserve a 10-20% margin.

Can a vortex air pump suck and blow at the same time?

Yes, the blower has independent suction and blowing ports, which can simultaneously perform negative pressure adsorption + positive pressure blowing; note that the inlet and outlet must not be directly short-circuited, as this will cause overload and high temperature.

Can the blower operate continuously for 24 hours without stopping?

Leynow 2HB/4HB industrial models support 24h continuous operation, but ventilation and heat dissipation must be ensured; for dusty working conditions, a pre-filter must be installed to protect the impeller.

What supporting accessories are needed for high-pressure blowers?

Commonly used: intake filter (mandatory for dust prevention), pressure relief valve (overload protection), silencer (noise reduction); Leynow can supply the complete set.

Can you provide accessories and repair and maintenance?

Yes, complete accessories such as filters, pressure relief valves, and silencers; provide technical consultation, troubleshooting, and factory repair and maintenance.
