Jetstream 5 pneumatic air turbine starter
The Jetstream 5 is a heavy-duty air starter motor for engines up to 80 litres, built for maximum reliability in harsh environments.
Manufactured from high-grade materials and ATEX compliant, the Jetstream 5 delivers safe, spark-free performance in marine, offshore, and hazardous industrial applications.
SOLUTION DETAILS
Built for large engines
The Jetstream 5 air starter motor is engineered to start engines up to 80 litres. Its rugged design and high-grade materials provide outstanding resistance to wear and damage, making it an excellent choice for demanding applications.
Marine and offshore ready
The Jetstream 5’s durable construction and corrosion resistance make it particularly suited to marine and offshore environments where reliability is critical.
Pre-engaged starting
- Outboard bearing: Outboard bearing starters have a nosecone and the drive shaft is supported at both ends. Because of this support they can be made shorter and more robust than overhung starters, which have a cantilevered pinion. The engagement principle is similar to overhung starters in that they only begin to rotate once fully engaged. Available on Jetstream 5 only.
- Overhung: Overhung starters have no outboard bearing or nosecone and as such pocket depth or starter indexing is not an issue. Being pre-engaged, they first engage into the ring gear whilst stationary and only once they are fully engaged do they begin to rotate. This system ensures that the starter cannot rotate prior to being engaged with the ring gear, thus reducing wear and the risk of sparking. Pre-engaged starters are a requirement of the European ATEX directive. Available on Jetstream 4 and 5.
ATEX-approved for hazardous environments
The Jetstream 5 conforms to ATEX EN1834-1 and EN1834-2, ensuring suitability for explosive gas atmospheres and combustible dust environments such as underground mining. Safety is enhanced by its cast iron construction and pre-engaged design, which removes the risk of sparks.
Flexible and low-maintenance
Available with integrated relay valve, exhaust adaptors, and mufflers to reduce fitting time. Operating at low (3 bar), medium (10 bar), or high (30 bar) inlet pressures, the Jetstream 5 is virtually maintenance-free and requires no lubrication. An optional beryllium-copper non-spark pinion provides further safety in hazardous conditions.
The Jetstream 5 sits within our full pneumatic starter motor range, built for high-torque air starting on the largest diesel and gas engines.
