PET-FK
Main features
• Perforated ceiling diffuser for extract air in fixed ceilings
• Cleanable commissioning box – FK
Description
Perforated air diffuser for most types of premises where an adjustable distribution pattern is desired.
• The diffuser is mounted as standard in a cleanable commissioning box type TK or FK that contains measuring hoses and adjustment dampers.
• PET/PETI for supply air can be delivered with 1-, 2-, 3-, or 4-way distribution (specified when ordering). Distribution pattern must be specified at order placement, otherwise the producct is supplied for 4-way distribution.
The distribution pattern can also be adjusted subsequently using the air deflector accessory AP (sold separately).
• PET can be used without a commissioning box. Commissioning must then be made with a separate damper.
• PET is designed for mounting in fixed ceilings.
• PETI is designed for flush mounting in 'false' ceilings, i.e. modular ceiling systems (595x595 mm).
• DS: spacer frame for recessed installation.
• MN: muff/nipple, duct extension for installation with a comissioning box in suspended ceilings.
• PET: Frame and front made of galvanized steel sheet, powder-coated with white RAL standard color, other colors are available.
• PETI: Frame and front made of galvanized steel sheet with aluminum frame, powder-coated in white RAL standard color, other colors are available.
• Commissioning box: Hot-dip galvanized steel sheet, internally insulated with washable and surface-coated sound absorber made of 100% recycled, non-allergenic, hydrophobic PET plastic material.
• For general product specifications, see separate document Product Specification that can be downloaded from our website.
• The product is connected directly to the commissiong box.
• The connection between the diffuser and the commissiong box can be extended with a circular piece of duct. If the connection exceeds 500 mm, an extension of the measuring hose and damper cords is required.
• When installed in a suspended ceiling, the MN accessory can be used, which extends the connection by 40 mm.
• The commissioning box is connected to a circular duct. Connection to a straight-mounted flexible duct is possible but not recommended.
• The commissioning box can be installed directly after a bend. When installed after a T-piece, a straight section of 4 x the duct diameter is required for mesuring accuracy.
• The diffuser's front plate is easily opened using, e.g. a credit card-sized plastic card, which enables easy installation and maintenance.
• Air deflector AP (accessory), is installed in the spring-loaded center pin of the diffuser front.
