For the precise and low-impact discharge of seed with pneumatic seed drills or granules with fertilizer spreaders, the hydraulic blowers used must control an aerodynamic operating point with both high pressure and volume flow, so that a high yield can be achieved.
Similar technical requirements must be covered by blowers used in air-assisted combine harvesters or plant protection sprayers for fruit orchards or vineyards. However, a somewhat lower air output is often required here, as crop protection sprayers tend to be more compact in design due to their area of application.
In addition to the air technology requirements, the demands for the lowest possible ecological footprint of agricultural equipment are also increasing, and with them the acoustics and energy efficiency of the blowers used. Hydraulic blowers for pneumatic drills should operate as quietly as possible, particularly in the vicinity of residential areas, but also to protect wildlife in the immediate vicinity. In times of rising raw material costs, the energy efficiency of the blowers used in semi-mounted or mounted seed drills, combine harvesters or over-the-row equipment is becoming increasingly important for environmentally friendly agriculture.
Seeding, Spraying, Harvesting Blower Kits
Seeding, Spraying, Harvesting Kits
The Seeding, Spraying, Harvesting blower kits are specially designed for seeding drills and fertilizers, plant protection sprayers and air assisted cutting units for combine harvesters. For these applications, punker offers configuration options with backward-curved as well as forward-curved fan wheels. Both options feature a very compact, robust and corrosion-resistant aluminum design. The forward curved impeller generates a very high power density (high volume flow, high pressure) in a comparatively small installation space, while the backward curved impeller achieves a comparatively high efficiency. Both options are used in the same housing configurations and can therefore be very easily interchanged depending on the machine configuration, which allows optimum matching to individual customer operations with low component diversity.
Benefits
Lower service costs
compared to blowers with plastic housing, as robust aluminum housing with optimized material thickness contributes to longer service life.
Easier maintenance and installation
than steel-housed blowers thanks to lightweight aluminum housing.
Energy cost savings
due to reduced energy consumption of the highly efficient backward curved fan impeller*.
*refers to type Xagri HL45
Flexible system design / easy replacement
Available with standard 6" and 8" connection dimensions and in two directions of rotation.
Fast and cost effective delivery
by consignment from Europe or optionally USA without customs clearance.
Applications
- Pneumatic seed drills / seeding machines / seeders
