The Franke Filter manufacturer

FRANKE-Filter GmbH was founded in Germany over 30 years ago, specializing exclusively in industrial oil mist elimination for power turbines and compressors. Equipment complies with API 614 standards and European ATEX explosion-proof directives.

Selecting Franke Filter Systems by Nameplate and Turbine Data

To select the correct Franke Filter oil mist separator or replacement cartridge, begin by photographing the factory nameplate. The metal plate specifies the FF2 series designation, model code, serial number, and year of manufacture.

If the nameplate is missing or illegible, supply turbine manufacturer details, rated output, lube reservoir capacity, and pipe connection dimensions. For large turbomachinery, specify required extraction air volume in cubic meters per hour.

Deep Microfibre Coalescing Technology of MFK Cartridges

Franke Filter FF2 series systems utilize high-efficiency mechanical coalescing principles without electrostatic charge. The filter medium consists of borosilicate micro-glass fibers arranged in a graduated porosity depth matrix.

Sub-micron aerosol droplets down to 0.1 micrometers collide with microfibers and coalesce into macroscopic droplets draining downward via gravity. Operational lifespan of genuine MFK cartridges reaches between 20,000 and 30,000 running hours.

Precise Lube Tank and Bearing Cavity Depression Control

The primary objective of an oil mist separator is maintaining steady negative pressure inside lube reservoirs and bearing housings. Optimal depression ranges between -2 mbar and -10 mbar depending on turbomachinery configuration.

Controlled vacuum prevents hazardous oil mist escaping past shaft labyrinth seals under high rotor rotation speeds. Systems regulate depression using variable frequency drive blower motors or precision mechanical control dampers.

Oil Recovery Loop and Environmental Compliance

Franke Filter separators provide a closed-loop oil recovery process that eliminates toxic liquid industrial waste generation. Coalesced clean oil collects in the conical vessel sump and drains back into the primary oil reservoir via a siphon trap.

By returning captured lubricant, expensive turbine oils are conserved while exhaust air discharged contains less than 1–2 mg/m³ of residual aerosol. This emission level fully complies with international environmental purity directives.

FLT486 Replacement Elements for General Electric Turbines

For operators of GE Frame 6, 7, and 9 gas turbines, Franke Filter manufactures FLT486 high-performance replacement cartridges. These elements serve as direct drop-in replacements for General Electric OEM part number 328A7187P003.

FLT486 elements match factory GE mounting flanges and vessel dimensions without requiring mechanical modifications. Installing FLT486 cartridges guarantees 99.99% oil separation efficiency, preventing lubricant carryover into compressor intakes.

Duplex 2x100% Redundant Skids for Continuous Power Generation

Base-load thermal power plants and pipeline compressor stations require continuous operation without shutdowns for filtration service. Franke Filter delivers fully redundant 2x100% duplex oil mist elimination skids engineered for uninterrupted duty.

The duplex layout incorporates two parallel filtration vessels with dedicated MFK cartridges and independent exhauster blowers. Switching between primary and standby circuits is performed using a 3-way valve without disturbing tank vacuum.

API 614 Standard Compliance and ATEX Explosion Safety

Franke Filter equipment is engineered in full compliance with the American Petroleum Institute API 614 international engineering standard. The standard governs lubrication, shaft-sealing, and oil mist removal systems for petroleum and gas installations.

For hazardous industrial zones, separators are manufactured in explosion-proof execution adhering to European ATEX directives. Pressure vessels are fabricated from coated carbon steel or marine-grade AISI 304 and AISI 316L stainless steel alloys.

Installation, Commissioning and Maintenance Support

Franke Filter FF2 separators mount directly onto lube reservoir access covers or adjacent structural steel mezzanine decks. The suction pipe runs with a steady slope toward the tank to prevent oil pocket accumulation and hydraulic shock.

The oil drainage line connects back to the lube console through an engineered liquid siphon trap. Routine maintenance involves monitoring differential pressure indicators to replace MFK cartridges every 20,000 to 30,000 hours.

System availability, replacement element pricing, and delivery schedules are calculated specifically based on your turbine or compressor engineering parameters. Official distributorship is not claimed.
