Defitec have over 20 years of worldwide extensive experience with replacement cartridges for urban, industrial, inland, coastal and desert gas-turbine sites. We offer guaranteed customer satisfaction in spite of extremely hostile environmental conditions such as dust, sand or snow storms, low and high temperatures and high-humidity exposure, as well as:

• High-quality and excellent performances: high-efficiency, high dust-holding capacity, low pressure drop and long life to better protect your large investment
• No alteration nor any modification of existing air intake filter systems necessary
• Fast response, technical assistance, flexibility, short delivery terms
• Impressive reference list of major customers in Europe, Africa, Middle East and Asia

Defitec replacement air-filters for gas-turbine air intake

A wide range of Defitec air filter element-cartridges are available, including: cylindrical, conical, V-pack and panel with multiple ways of fittings: vertical or horizontal yoke, hand crank rod, flange-top or twist locked bayonet.

We offer high-performance media providing protection against erosion, fouling and blade corrosion:

Cellulose and synthetic fibres

Our unique blend of cellulose and synthetic fibres:

• With optional additional layer of nano-fibres to capture sub-micron particles
• With optional flame retardant to reduce the ever present risk of fire to the bare minimum (it will self-extinguish once the source of ignition has been removed)

100% premium grade synthetic fibres

We can provide a premium grade of media to fit your specific operating conditions, matching environmental requirements such moisture, fog, humidity and storms and designed to provide very high filtration-efficiency, extra long lifetime and minimum operational pressure drop in order to keep the turbine output at the maximum.

Defitec replacement air-filters offer the following benefits:

• DefiLock feature keeps uniform pleat spacing to improve the efficiency of the air pulse system and to increase the cartridges replacement time by at least 60 %
• Efficient dislodgment of the filter-dust cake when the reverse air pulses, even in very cold or hot atmosphere and high humidity content
• Sturdy construction, excellent reliability, high-durability in the toughest environments
• Pleats held in place with hot-melt adhesive beads are deposited at regular intervals on liners, to hold the pleats evenly spaced and to bind them securely to the liners, providing extra strong mechanical resistance on the media during pulse cleaning
• Each cartridge with its own seamless polyurethane gasket, of strong adhesion to end open cover, moulded in place to ensure an airtight seal for exposure in any compression, humidity and temperature
• Over 70,000 conical / cylindrical cartridges sets (one of the most popular air intake system) supplied to around 50 power plants worldwide with not a single failure
