Alfdex

What Alfdex does

Alfdex AB is a Sweden-based industrial joint venture, owned 50/50 by Alfa Laval and Concentric since 2011 (originally formed with Haldex in 2002), that designs and manufactures hardware for cleaning crankcase gases and providing thermal management in commercial vehicles and off-road equipment. Its flagship product, the g-Cleaner, is a centrifugal disc separator that operates at 2,500-3,000 g-forces to remove oil mist and particulates from crankcase blow-by gases, achieving near-100% separation efficiency, a maintenance-free sealed-for-life design (rated L10: 8 years / 1.2 million km / 20,000 hours), and compatibility with EURO 6, EPA 13, Stage 5, Tier 4 Final and forthcoming EURO 7 / EPA 27 standards. The newer g-Heater applies patented catalytic combustion to deliver near-zero-emission battery temperature management and cab heating for battery electric, fuel cell, and hydrogen commercial vehicles, extending BEV range by up to 20%. A service-kits aftermarket business complements the OE supply contracts.

Alfdex operates a two-tier technology platform: oil-driven (using surplus engine lubrication pump flow) and electric motor-driven variants of the separator, with the electric Medium Duty (eMDS) and Super Duty (SDS) units representing the current generation. The company is headquartered in Landskrona, Sweden, with production in Landskrona and at the Alfa Laval Kunshan facility in China (since 2018), R&D in Tumba and Huddinge/Flemingsberg, and a North American commercial office in Itasca, Illinois (via Concentric Itasca). Thirteen global assembly lines support an installed base of more than 10 million separators, including the majority of new heavy-duty trucks produced in North America, China, and Europe. The business is certified to IATF 16949, ISO 9001, ISO 14001, and ISO 45001, and has received customer quality awards from John Deere (Partner-level, 3+ consecutive years), Weichai (Gold Supplier), and Liebherr (96/100 in VDA 6.3 audit).

Commercially, Alfdex sells almost exclusively into enterprise OEM platforms through multi-year supply contracts (recent disclosed programs total approximately SEK 1.3 billion over 5-8 years and SEK 2 billion+ over 10 years), with named enterprise customers spanning Daimler, Volvo, Scania, MAN, Navistar, Weichai, John Deere, AGCO, Volvo CE, Volvo Penta, MTU/Rolls-Royce, and Liebherr. Distribution is reinforced by global aftermarket partners including Automann USA (since 2023) and Dorman Products (since 2022) for service kits in North America, and a network of European distributors. The g-Technology portfolio, including the g-Cleaner, g-Heater, and g-Technology trademarks, is the company's core commercial identity and is supported by ongoing R&D collaboration with Chalmers University of Technology on hydrogen engine applications.

Revenue model

1. Original Equipment (OE) – g-Cleaner separators: Alfdex supplies g-Cleaner crankcase oil mist separators to major truck and off-road vehicle OEMs worldwide. Units are designed into new engines; revenue is generated through long-term supply contracts with major global manufacturers. Two recent program contracts total approximately SEK 1.3 billion.
2. g-Cleaner SDS – Super Duty Separator (On-road): Eight-year program for large on-road engines (trucks and buses) with a global OEM/powerhouse vehicle manufacturer. Estimated total value of approximately SEK 1,000 million. Revenue recognized over the multi-year program lifecycle.
3. g-Cleaner eMDS – Electric Medium Duty Separator (Off-road): Five-year agreement with a major off-road agriculture and construction equipment manufacturer. Estimated total value of approximately SEK 300 million.
4. g-Heater – Prototype and Series Production: Prototype order received from a major truck OEM for the new g-Heater battery temperature management and cab heating product. Revenue stream expected to grow as product moves from prototype to series production for BEVs, fuel cell, and hydrogen vehicles.
5. Aftermarket Service Kits: Service kits for most Alfdex products on the market, sold via the independent aftermarket through distributors (e.g., Automann USA, Dorman Products). Shelf-ready kits with cross-reference part numbers, packaging, and installation instructions. Kits include complete housings with discs and connectors.

Core offering

Alfdex designs, manufactures, and supplies centrifugal disc separators (g-Cleaner) that clean crankcase gases from on-road and off-road combustion engines, plus a catalytic combustion heater (g-Heater) for battery temperature management and cab heating in commercial vehicles. The product portfolio is sold primarily to global commercial vehicle and engine OEMs under multi-year supply contracts, with aftermarket service kits distributed through independent parts distributors.

Product overview

Alfdex is a 50/50 joint venture between Alfa Laval and Concentric, offering a focused portfolio of two core products under the g-Technology brand. The flagship product, the Alfdex g-Cleaner, is a world-leading oil mist separator for cleaning crankcase gases in combustion engines, using centrifugal separation technology. The newer Alfdex g-Heater provides catalytic combustion-based heating for battery temperature management and cab heating in electric and fuel cell vehicles. Both products are supported by aftermarket service kits. The g-Cleaner is currently installed in over 9 million heavy trucks globally and has prevented over 100 million liters of oil from being released into the environment annually.

Direct peers

• Mann+Hummel: Global filtration specialist serving automotive and commercial vehicle OEMs with oil, air, fuel and emissions-related filter systems; directly comparable to Alfdex in delivering engine ancillary filtration and crankcase/emissions-side components to major truck and off-road OEMs.
• Donaldson Company: Industrial and vehicle filtration manufacturer whose engine and crankcase filtration range competes head-to-head with Alfdex's g-Cleaner concept among heavy-duty truck and off-road equipment OEMs.
• Cummins Filtration: Filtration arm of Cummins providing OEM and aftermarket filtration solutions (oil, air, fuel, coolant, crankcase ventilation) for heavy-duty diesel engines — directly overlaps Alfdex's crankcase ventilation and heavy-duty engine aftertreatment-adjacent categories.
• Baldwin Filters: Heavy-duty filtration brand supplying replacement filters for commercial vehicles, off-road and industrial equipment; comparable to Alfdex's aftermarket service-kit position in independent distribution channels.

Broad incumbents

• Parker Hannifin: Diversified motion and control technologies supplier providing engine, fuel, emissions and filtration components to commercial vehicle and off-road OEMs; overlaps Alfdex's fluid/filtration/centrifugal domain at a much broader portfolio scale.
• Bosch (Automotive Aftermarket / Powertrain): Global Tier-1 systems supplier of ICE and electrified powertrain and emissions components for commercial vehicles; competes in engine-side components and exhaust/emissions management relevant to Alfdex's crankcase ventilation and g-Heater thermal management.
• Mahle (Filtration & Engine Peripherals): Major Tier-1 supplier of engine peripherals including oil management, filtration and thermal management components for passenger and commercial vehicles; overlaps Alfdex's engine ancillary and thermal categories at incumbent scale.

Others

• Concentric: 50% parent of Alfdex, specializing in fluid dynamics and fluid power technologies for trucks, buses and off-road vehicles; the relationship and technology overlap makes it the closest analog to Alfdex's core competency in centrifugal fluid handling for commercial vehicles.
• Alfa Laval: 50% parent of Alfdex and the originator of the underlying 100+ year centrifugal separator technology; Alfdex is in essence an internal spin-out of Alfa Laval's separation platform, making the parent itself the closest functional and technical analog.

Emerging players
