Filter separator vessels for reliable filtration of jet fuel, diesel and aviation gasoline.
Coalescers
Coalescer housings for separating water and solids from hydrocarbon streams.
Micronic Filters
Fine particulate filtration housings for applications requiring high fuel cleanliness.
Clay Filters
Clay treatment housings for removing surface-active agents, color bodies and additives where required.
Cartridge Systems
Cartridge filter systems for industrial, environmental, water treatment and process applications.
Relaxation Tanks for Safe Transfer
Static charge control can be just as important as filtration efficiency when handling hydrocarbon fuels downstream of filters.
After-filtration hold time.
Because filtration equipment is one of the strongest static generators in a fuel handling system, filtered product often needs controlled residence time before it enters equipment with vapor space. Vertical relaxation tanks provide that hold time in a compact pressure vessel layout.
See standard relaxation tank sizes.
Lemico relaxation tanks are designed around product, flow, pressure and operating requirements, with standard reference sizes available from 100 to 1,500 US gallons.
Standard Housing Design
Filter housings can be engineered around aviation fuel filtration standards, pressure vessel code requirements and service access needs.

Vertical Coalescer Separators
Vertical coalescer separator housings can be configured for commercial and military aviation fuel filtration duties.
Commercial aviation fuel.
Category C, Type S coalescer separator housings are used for commercial aviation fuel applications. Type S qualification is intended for filtration points where significant levels of water and dirt may be expected in the product.
Military fuel applications.
Category M, Type S coalescer separator housings support military F24, JP-8 or JP-5 fuel filtration requirements, with configurations reviewed around system flow rate, cartridge selection and installation needs.
Horizontal Coalescer Separators
Horizontal coalescer-separator housings can be configured for military mobile fueling operations where compact, lightweight packaging and high flow rates are important.
Category M, Type S-LW.
Type S-LW coalescer-separator housings are used for military mobile fueling applications where minimal water and particulate contamination are expected. Dual-stage systems support fuel-water separation and solids removal in a compact horizontal configuration.
Mobile fueling integration.
Horizontal housings can be reviewed for Category M fuels, quick-connect system integration, field identification, cartridge stability and service access requirements.
