Pulse Jet Cartridge Filter

<h2>Pulse Jet Cartridge Filter (Conical & Cylindrical / Cylindrical & Cylindrical)</h2> The filter cartridges are especially designed to meet the strict demands of gas turbine air filtration systems. The filter media used in these filters provides high protection to gas turbines. The outstanding durability and the high efficiency of the filter media decreases the risk of dust entering due to media failure or due to high dust penetration. The filters are available in both, self-cleaning pulse and static type and are suitable for vertical and horizontal design. Typical range from F7 or MERV 13 up to EPA grade.

Augmented Self Cleaning Filters

Developed by AFI, Augmented Self Cleaning Filters are designed for gas turbines and diesel engines operating in high-dust environments. They employ inertial separation to remove up to 75% of intake dust before it reaches the filters. The remaining particles are captured by filters. A reverse pulse of compressed air cleans the filters, and the extracted particles are removed through a secondary air circuit, preventing re-entrainment and maintaining low differential pressure. These filters feature self-cleaning synthetic-cellulose media that resists humidity, extending filter life. A moulded gasket ensures an airtight seal, preventing air bypass. The durable galvanized steel frame construction protects the media packs, making them suitable for high-dust environments.

Sand Trap Filter

<span style="font-weight: 400;">A Sand Trap Air Filter is a type of pre-filter used in HVAC systems and industrial air handling units, especially in environments where sand, dust, or large particles are prevalent—like deserts, cement plants, or coastal areas. It is not a fine air filter, but it plays a critical role in protecting downstream filtration systems and mechanical equipment.</span>

Air Pre-Heater / Anti Icing Filter Housing

Anti-icing technology for suction air filters is crucial in preventing ice accumulation that can obstruct airflow, increase pressure drop, and reduce the efficiency of systems like gas turbines. Various methods are employed to mitigate these issues.

Air Filter Inlet Silencer

AFi can provide various solutions to the problems presented by air induction noise through the use of various forms of annular or rectangular intake silencers. These can be made in an appropriate size to suit the characteristics of the flow system. The available designs vary from the simple annular ?clean straight-through? acoustically packed intake silencers, or designs with a central pod or annular splitters. These units can be placed between the engine and the corresponding filtration unit.

Suction Air Filter Housings

<span style="font-weight: 400;">Suction air filter housings are critical components in turbo compressors and gas turbines, ensuring that incoming air is clean and free from contaminants. These housings protect internal components from damage due to particulates, moisture, and corrosive elements, thereby enhancing performance and extending equipment lifespan.</span> <span style="font-weight: 400;">Suction air filter housings are designed to remove particulates and contaminants from the air before it enters turbo compressors and gas turbines. They typically incorporate multi-stage filtration systems to handle various environmental conditions: </span>   <ul style="margin-top: 20px; margin-bottom: 20px;"> <li style="font-weight: 400;" aria-level="1"><b>Pre-filters</b><span style="font-weight: 400;">: Capture large debris and coarse particles.</span></li> <li style="font-weight: 400;" aria-level="1"><b>Intermediate filters</b><span style="font-weight: 400;">: Remove medium-sized particles.</span></li> <li style="font-weight: 400;" aria-level="1"><b>Final filters</b><span style="font-weight: 400;">: Eliminate fine particulates to ensure clean air reaches the turbine or compressor.</span></li> </ul> <span style="font-weight: 400;">These housings are often modular, allowing for customization based on specific site requirements, and can include additional features like mist eliminators and evaporative cooling systems. </span> <p style="font-size: 22px; margin: 20px 0; font-weight: bold;">Types of Filter Housings: -</p> <p style="font-size: 22px; font-weight: bold; margin: 20px 0;">A. Static Filtration Systems:</p> <img class="alignnone size-medium wp-image-1140" style="display: block; margin: 20px 0;" src="https://www.afiindia.com/wp-content/uploads/2025/05/5af0f485-0a4b-4ddb-9d7d-c01a3a77a17d-300x300.jpg" alt="" width="300" height="300" /> <p style="font-weight: 400;">Inlet static air filtration systems using replaceable media are engineered to purify air streams by removing fine particulates, ensuring the protection and efficiency of equipment like gas turbines and compressors. These systems are particularly effective in environments with high concentrations of fine, sticky, or light particles that are challenging to eliminate using self-cleaning mechanisms.</p> <p style="font-size: 22px; font-weight: bold; margin: 20px 0;">B.

High Efficiency Water Droplet Separator (WDC-AFI)

Water Drop high efficiency droplet separators are designed for demanding applications such as oil & gas, chemical, energy and marine industries, where reliability, easy installation and special design play an important role. Droplet separators are designed to restrict the passage of moisture, salt spray, rainwater and airborne aerosol particles e.g. into HVAC systems, engine room intakes, machinery spaces, and diesel and gas turbine air intakes. Water Drop depends on many variables such as size of the separator, wind circumstances, face velocity, air temperature and relative humidity. <img class="alignnone size-full wp-image-1156" src="https://www.afiindia.com/wp-content/uploads/2025/05/2ab7b88d-71db-41c8-b969-4fd6afb0b9f7.png" alt="" width="258" height="228" />

Rotary Oil Bath Filter / Auto Viscous Filter

AFi's Auto Viscous filter is a self cleaning viscous filter using a rotating curtain of metal panels as the filtering mat. Behind the filter mat is an endless roll of oil drop eliminator. A timer controlled, totally enclosed thermally protected geared motor rotates the filter media & oil drop eliminator which pass through a viscous oil bath located at the bottom of the filter. The viscous oil cleans the filter media & the oil eliminator minimizes the carry over oil droplets into the air stream. The sludge collected in the oil bath needs to be cleaned periodically.

MPR Series – Reverse

MPR pocket filters are unique premium coalesce pre-filters in reverse air flow direction. The MPR pocket filters serve as efficient pre or final filters in air intake systems of Gas turbines in any environmental condition (including off-shore, marine) and in any climate (including tropical). They efficiently remove air borne particulate matter but also snow, mist and fog acting as a filter and a coalescer in one. MPR filters are specially designed for the elimination of free water and air borne salt crystals. Where subsequent final filters are placed, they protect them not only from coarse dust but also from running in wet conditions. The MPR filters do significantly prolong the filter life time of the final filter and also increase their operational safety.
