Product technical indicators:

1. Appearance: There should be no scratches, sanding, rust and other defects on the

surface. The surface treatment should be evenly applied. There should be no defects such

as scratches, scratches, shrinkage and deformation, and uneven color on the surface of

plastic and rubber parts. Equipped with 10pcs gas cylinders and 4pcs net cover, the

products are packaged in aluminum alloy box.

2. Quality: ≤1.0kg

3, the largest external dimensions: head diameter ≤ Ф 120mm, handle diameter ≤ Ф 50mm;

length ≤ 340mm.

4. Net length: ≤18mm, net area ≥12m2.
5. Convenient operation: The pneumatic catching net should be easy to carry. Its various

moving parts should be flexible in operation, reliable in connection, easy to break, easy to

reset the switch, and easy to recycle and install.

6, the quality of the traction head: ≤ 25g.

7. Rubber sleeve airbag: used to cushion the airbag part ≥ 2mm.
8. Thickness of rubber sleeve: ≥1.5mm.
9. Net tensile strength: ≥200N.
10. Flight speed: The speed of the measured network should be ≥30m/s from the

transmitting direction of the network at a distance of 3m from the transmitting end; the

measured network speed should be ≥7m/s at a distance of 10m from the transmitting end

along the transmitting direction of the network.

11. Safety: The pneumatic catching net should have a safety device. When it is in the

insurance state, it cannot be launched; the impact energy of the traction head at 6m

(plywood bullet marks) should not cause harm to the human body.

12. Effective working distance and spreading distance: The effective working distance of

the pneumatic catching net is 6~18m. The launched catching net should be unfolded within

the effective working distance range, and there is no abnormal phenomenon such as

staggered winding of the traction head. The throwing area within the effective working

distance range is ≥3m2.

13. Function and Accuracy: The pneumatic catching net is within the effective range of

action, and the optional human body target is placed at a certain point, aiming at

simulating the launching and catching net of the human target head. The catching net

should cover the simulated human target, and the maximum distance from the surrounding

edge of the catching net to the ground is ≤0.5m.

14. Volume of gas storage tank: 100~120ml.
15. Environmental adaptability: It should be able to be used normally in the environment

of low temperature (-20℃) and high temperature (50℃), the range is ≥12m; the range after

immersion is ≥11m.

16. The product fell from the height of 1.2 meters head upwards, horizontally, and head

down three times on hard soil. The drop process was not fired, no damage, and no failure

to launch.
