FRP DUCTING ODOUR/CONTROL SYSTEMS
FRP Ducting... Proven longevity, smooth internal surface and reduced long term fouling.
||From highly corrosive fume origins to their ultimate dispersal, Maskell Productions have designed and built the equipment capable of handling, moving, cleaning and dispersing them.
Maskell have 30 years experience in the design and manufacture of fibreglass ducting systems and associated equipment. Maskell produce a complete range of ducting, bends, tees, flanges, reducers, dampers, and other accessories fabricated in corrosion resistant glass reinforced plastic (GRP).
Maskell design duct systems for specific projects with consideration of pressure, span and external load requirements. A range of resin systems and manufacturing processes are used to optimise the duct system for the application, from mild waste air duct work to aggressive chemical duct handling caustic or sulphuric acid systems and elevated temperature service.

Advantages of GRP Ducting
Fibreglass duct offers several advantages over
traditional materials including:
||Installation of lightweight duct in 10-20m lengths
offers lower handling and cranage costs.
||Smooth internal surface and reduced long term
fouling offers lower fan power costs and enables
reduced duct diameters. We suggest review at
the design stage of the blower requirements for
smooth bore duct with reduced lifetime fouling.
||Reduced whole of life cost on the duct due to
savings in maintenance and fan power costs.
||Use of butt-strap site laminated joints means no
leaks and a 100% leak test of the duct system is
practical. However clients may request flexible
couplings which are also offered, as necessary.
||Proven longevity of fibreglass duct including use
for acidic, alkaline and waste gas streams.
||Installation with sand or aggregate bedding for
buried ducting to suit locally available material.
Fibreglass Duct Specification
Fibreglass (GRP) ductwork supplied by Maskell Productions
is fabricated to meet customer design requirements.
Maskell can manufacture any size or shape FRP Duct, fitting
or accessory that your process may require.
All equipment is
manufactured in house, giving the ability to construct standard
and special fitting shapes, sizes and transitions. All ductwork is manufactured to meet or exceed the Australian
Ducts are filament wound or laminated CSM construction to
meet the design requirements.
Design is to ensure adequate
strength under the specified design pressure, support spans
and external loads.
Duct is internal diameter series and is
molded to give an accurate, smooth internal surface. Available
in custom lengths or standard 10 and 20 metre lengths.
Internal / External Finish
All external ductwork is finished with a UV resistant gelcoat. Duct is suitable for above ground service in an open environment on site.
All ductwork is to have a molded internal surface finish for maximum chemical resistance.
This also ensures minimum duct head loss in the system and resistance to algal growth and fouling of the ductwork.
Note that no further coatings or corrosion protection are required on fibreglass duct. The external gelcoat should provide 25 years service before recoating is required.
Ducting is manufactured from a resin system suitable for continuous service for the design temperature and chemical environment.
Resin systems used include isophthalic and vinylester resins. Refer chemical resistance guides for resin selection.
