1: Optimal Sealing by O-Ring
Highly durable Teflon O-Ring was used and special coating
was done at the contacting point of O-Ring to ensure perfect
Sealing and secured operation at fire detecting.
2: Shock proof structure with steel ball support method
With 8 steel ball support structure for shock esistance,
it Is reliably safe from external impact and free from
damage And leakage
3: Low Assembly Load
By minimizing the assembly load with o-Ring Sealing Method,
safety is secured with low pressure inside the Head.
4: Excellent Design
As the head is installed in the building, aesthetic design By
minimizing heat detecting with small head was made.

Fireguard has quick response & standard responce sprinklers with durable design which utilizes a 3mm frangible glass ampule as the thermosensitive element for quick responce and 5mm for standard responce. This provides sprinkler operation approximately six times faster than ordinary sprinklers. While the quick response sprinkler provides an aesthetically pleasing appearance, it can be installed wherever standard spray sprinklers are specified when allowed by the applicable standards. It offers the additional feature of greatly increased safety to life and is available in various styles, orifices, temperature ratings and finishes to meet many varying design requirements.
