jet nozzle diffuser

Jet Nozzle APK series


Characteristic

We use the spheroid seamless wielding technology to In order to reduce the resistance of spraying.

Characteristic

Material

Spheroid and decoration circle use aluminum material, connection part and saddle shape control made of cold galvanization steel plate. The product surface may process pure white (RAL9010) or the other RAL-standard color according to the request.

Material

Jet nozzle profile

Jet Nozzle mainly uses in the air conditioning supply-air outlet and the environment which has large people flux.

When the public place area is large (for example, some halls and assembly shop), we can not achieve the effect by using ceiling diffuser , in this situation,we need to install jet nozzle in the side to blast. In the situation where outlet and the room temperature changes constantly, the blast air current will be upward (hot blast) or downward (cool wind) offset. The blast direction also possibly receives the disturbance from external factor, like partial convective current or crossflow. Therefore, some model's jet nozzle may be designed as a revolving way.

The blast's direction may be changed by hand, and also may be swing in 30° scope with electricity. We may provide manual operated or the electrically operated control system according to the user need. because uses of the best aerodynamics structural design, it has achieved the ideal noise control, also as a result of its high quality's contour design, it may be used in the music hall, the theater, the museum and other places.

We provides each models of jet nozzles, suits for every kind of room condition and the technical requirement, can satisfy the very high noise request, may be used in every ventilation equipment.

Drum Louver


Use

The drum shape supply-air outlet is mainly suitable for the air conditioning ventilation system's blast. like stadium, airport, exhibition center, industrial production workshop and so on large-scale place.

Characteristic

This product has the bidirectional adjustment blast angle characteristic, the amount of wind is big, blows of far, the adjustment is convenient.
The gusty area is the rectangular outer edge structure, in the outer edge the coverall drum shell, the drum shell may, in the pitching direction carries on ±30° in the scope to adjust.

Drum Louver

The linkage leaf blade may, in the horizontal direction carries on ±45° in the scope to adjust.
Changes the blast direction.
When necessary may install regulating valve (OBD) at the back of the gusty area to adjust the blast quantity.
Is the reduced noise, may install the amount of wind regulating valve on air hose's leg.
The gusty area solid of revolution and the frame body uses the PEF cotton and kapok seal, causes the leaking out quantity minimum.
The product surface may manages according to outside the user request static electricity spraying or the anode.

Variable swirl air diffuser


Characteristic

Variable swirl air diffuser

The AXK series has six kinds of specifications (315,400,630,800) to be chosen, the positive air outlet assembled with air deflector and turbine type blades, the blades could be adjustable by manual or by electric device to reach the goal of blast steadily.

Compare with common air diffusers, Because the blades are designed according to the principal of fluid dynamics, change the air current into speedy eddy current, thus increases cold and the hot blast depth and the cover area, causes the air current circulate sufficiently, achieves the best well ventilated effect.

Ball type jet diffuser


Explanation

The ball type jet diffuser are made according to the blueprint of the Fifth Ministry of Machinery Industrial ,Sixth Design Research.

This diffuser is suitable for the air conditioning, ventilated post blast. May adjust the airflow direction and the blast quantity through the self-adjustable device. this diffuser is easy to operate, the adjustment is flexible, the forehead can rotate, the slewing area is broad.

Ball type jet diffuser

Performance and specification

The ball type jet diffuser has 7 kinds of specifications, may choose according to the amount of wind, the local resistance coefficient ξ=1.2. The jet flow axle center speed changes, please see the diagram of curves one. The different wind quantity under different wind speed, please see figure one.
