SELECTION & SPECIFICATIONS
Selection & Specifications
How much energy does the blower save versus a conventional blower?
It saves 40-60% under equal duty versus conventional vortex and Roots blowers. Replacing a 7.5 kW vortex blower running 16 hours a day for 300 days a year at RMB 0.8/kWh saves about RMB 11,520 per year.
Which power ratings are available?
Eight models from 1 kW to 15 kW: H1.25P (1 kW), H2P (1.5 kW), H3P (2.2 kW), H5.5P (4 kW), H7.5P (5.5 kW), H10P (7.5 kW), H15P (11 kW) and H20P (15 kW), covering 500-2600 m³/h and 9-35 kPa.
How do I select a model by airflow and pressure?
Choose by required airflow and air-knife pressure, allowing a 10-15% margin for duct losses. For example, 1400 m³/h at 22 kPa calls for the H5.5P (4 kW). Send us your duty parameters if you are unsure.
How loud is the blower?
Measured sound level is 78 dB(A). Conditions: ducting connected, unit inside the acoustic enclosure, measured 1 m from the machine. The enclosure is standard across the range; this is a reference value that can be re-verified on your site.
TECHNOLOGY & STRUCTURE
Technology & Structure
Why ceramic ball bearings?
Ceramic ball bearings resist wear and high temperature, and combined with direct drive they make the system completely oil-free, eliminating contamination risk in food, pharmaceutical and electronics applications. They are standard from 1 kW to 15 kW with no downgrade at low power.
What is the advantage of direct drive over belt drive?
Direct drive removes belts and gearboxes for zero transmission loss and no wear-related efficiency decay. Conventional blowers lose efficiency and consume more energy as mechanical parts wear, and require periodic belt and gear oil replacement.
Does the blower need lubrication or mechanical maintenance?
No. Ceramic ball bearings with direct drive make the system completely oil-free and free of mechanical maintenance. Routine care is limited to replacing the intake filter every 1-3 months, shortened in harsh conditions.
What are the motor protection and insulation classes?
The motor is IP54 with insulation class CL.H (180°C); winding wire is rated 200°C, cooling is by air and duty is S1 continuous. Measured motor efficiency is 94% at 15,000-24,000 rpm.
INSTALLATION & SERVICE
Installation & Service
What are the installation environment requirements?
Operating and storage temperature is -20°C to +50°C with 10-95% humidity. Keep at least 0.3 m clearance in front of the intake. If ambient temperature exceeds 45°C, route the intake duct outside the line to ensure adequate cooling.
Can you supply export voltages and custom outlets?
Standard rated voltage is 380V AC; other regional voltages are available on request. The standard outlet is Φ100, switchable to Φ63 / Φ75 two-way or three-way manifolds. The blower head and VFD can also be mounted separately to suit different cabinet layouts.
What is the warranty and service response?
12-month unit warranty with extended cover on core parts. We respond within 10 hours of a service call and dispatch stocked core spare parts within 48 hours. Training on operation, routine maintenance and safety is provided, and solutions can be tailored to your process.
How often should the filter be changed, and what if it is not?
Change the intake filter every 1-3 months, shortening the interval in harsh conditions. A clogged filter can cause surge, reduce the energy saving achieved, and damage the motor bearings.
