Engine Protection System

Before it enters your engine, stop it.

Fuel and air carry water, impurities, particles, and dust. PurMotors technology places technical barriers at the points where your engine is most vulnerable.

Find the product for your motorcycle Discover the Protection System

Your engine breathes air and burns fuel.
Both need to reach it cleaner.

Two inlets. Two contaminated flows. Two barrier systems.

Flow 01

Fuel

From tank to injectors — three vulnerable points along the way.

Risks in the flow
  • Free water from condensation or refueling
  • Sediment and solid impurities
  • Suspended abrasive particles
PurMotors barriers
  • ✓H2O-Stop — 12 µm, 3 layers
  • ✓Pump Protector — 25 µm
  • ✓Fuel Pump Pre-Filter — 20 µm
Flow 02

Air

From the environment to the intake — a barrier adapted to the conditions.

Risks in the flow
  • Fine dust and sand
  • Airborne particles
  • Dirt drawn in off-road and in heavy traffic
PurMotors barrier
  • ✓Dual Use Air Filter — 15 / 25 / 40 µm
  • ✓Washable and reusable polyester
  • ✓Dry or oiled — adapts to conditions
Fuel flow

The fuel path:
three barriers before the critical components.

  1. System inlet
    Refueling
    free water impurities sediment
  2. Fuel Protection
    H₂O-Stop
    • —3-layer technical non-woven fabric
    • —Separates free water from gasoline
    • —Filters impurities down to ~12 µm
    • —Works right at the fuel inlet
    • —Catches water before the tank
    • —Does not alter the fuel's chemical composition
  3. Storage
    Fuel tank
  4. Pump Protection
    Pump Protector
    • —Technical polyester non-woven
    • —Filters solid contaminants at 25 µm
    • —Installed around the pump assembly, inside the tank
    • —Works ahead of the Pump Pre-Filter
    • —Shields the pump from solid contaminants
    • —Not an external component — it's integrated into the tank
  5. Critical component
    Pump assembly
  6. Injection Protection
    Fuel Pump Pre-Filter
    • —High-precision technical replacement part
    • —Filters down to 20 µm
    • —Protects the fuel pump and injectors
    • —Catches residual solid contaminants
    • —Part of the fuel system
    • —Installation at a qualified workshop
  7. Final destination
    Injectors
Airflow

One filtering barrier.
Three grades of protection.

PurMotors polyester operates dry in normal use. It can be oiled when fine dust, intense off-road riding, or severe conditions call for more protection.

Three versions — one for each condition
Street

Road · everyday use · city traffic

40 µm
Enduro

Mixed use · adventure · off-road touring

25 µm
Enduro Pro

Intense off-road · fine dust · extreme conditions

15 µm

Washable and reusable. Technical polyester made in Italy. No need to replace it at every service — wash it, dry it, refit it.

Technical proof

Numbers, materials, position:
the difference is technical.

H2O-Stop
~12 µm

Catches solid impurities in the fuel. Separates free water before it reaches the tank.

Pump Protector
25 µm

Shields the fuel pump from solid contaminants. Works ahead of the stock pre-filter.

Fuel Pump Pre-Filter
20 µm

Filters the fuel before it reaches the pump and injectors. A high-precision technical replacement part.

Dual Use Air Filter
15 /25/40 µm

Three levels of air filtration. Choose the version to match the conditions you ride in.

Material — H2O-Stop

3-layer technical non-woven

Multi-layer non-woven fabric. It separates free water through differences in surface tension, not chemistry.

Material — Pump Protector

Polyester non-woven

A physical barrier around the pump assembly. It holds back solid contaminants before they reach the moving parts.

Material — Air Filter

Washable polyester

Filters dry in normal use. Can be oiled when conditions call for protection from the finest dust.

Designed and made in Italy. Materials and a controlled Italian supply chain. GreenTek Hub — PurMotors.
