mechanical Smoke Vent system for factory

Our skylight is integral solution of natural ventilation, natural skylight and fire smoke exhaust. It's applied in many buildings such as industrial, commercial and public places.

In a fire, The most important function is to efficiently and quickly exhaust the smoke and heat to outdoors. a large amount of smoke and heat will be produced when fire. NSHEVS can be linked with FAS. When the NSHEVS receives the fire alarm signal, it will automatically open the flaps to exhaust smoke within 40 seconds, YOU KNOW,most of the victims were death by smoke rather than burned. so it can reduce the death,and in ususal,it can be used for natural ventilation and natural skylight, save electric bill of light and fan

TOPRISE has got more than 40 patents and created a seamless corner design for SKYLIGHT. All products are excellent about air tightness, water tightness, wind pressure resistance ,high snow load, high temperature resistance, low temperature resistance, etc. 

We supply with electric control or pneumatic control system. We have kinds of Arched Double Flaps ,Arched Single Flap,Triangle Double Flaps,Flat Double Flaps,

Arched type :suitable for northern areas with more snow, 

Flat slope type： suitable for areas with less rain and snow

We always use high- end raw material and experienced skills to produce high quality and reliable NSHEVS for clients.

Q: Could you customize the size?
A: Yes, we can customize the size as per your requirement.

Q: What's your MOQ?
A: 10 units each size.

Q: Could you recommend the model and quantity?
A: Yes, we can design the model and quantity as per the warehouse dimension and warehouse type.

Q:How about the lead time?
A: Normally 2-3 weeks. It depends on the quantity and our production plan.

FAS linkage intelligent double flaps

Superior wind load resistance and snow load

Seamless corner and superior waterproof

Temperature control release and remote control

Heat insulated aluminum alloy profile

Larger areas of natural skylight, ventilationand smoke exhaust

Intelligent Control System

The smoke vent can open to exhaust smoke automaticallyin case of fire. 

Each smoke vent unit can be monitored andcontrolled (showing the status 

of open, dose and error feedback).

1) Electric actuator is 24V DC. It has self lock function andlimit switch. Gas springs are 

equipped to realize three -point support and make sure its stability.

2) Pneumatic actuator has various emergency open measuressuch as common compressed air, 

control box emergencydevice, temperature sense of emergency. It's safe and reliable.Gas springs 

are equipped to realize three- point supportand make sure its stability.
