Tamrotor Marine Compressor E12 Code 50553344

Tamrotor Marine Compressor E12 Code: 50553344 Screw Air Compressor

The Tamrotor E12 (Part/Code: 50553344) is an oil-injected rotary screw air compressor engineered specifically for continuous duty in marine engine rooms, offshore drilling platforms, and harsh industrial environments. Manufactured to meet rigorous class society standards, the E12 platform delivers dependable low-to-medium pressure service air and control air under extreme ambient conditions, severe vibration levels, and fluctuating power supplies typical of shipboard switchboards.

Featuring Tamrotor’s proprietary asymmetric rotor profile, the E12 screw element is direct-coupled or belt-driven to ensure high volumetric efficiency and minimal thermal expansion stress. The integrated lubrication and separation circuitry maintain discharge oil carryover below 3 ppm, safeguarding downstream pneumatic control lines, emergency shut-off valves, quick-closing systems, and automation manifolds.

Frequently Asked Questions

What is the primary cause of high discharge air temperature on the Tamrotor E12?

High discharge temperature is almost always caused by a jammed thermostatic bypass element, clogged oil cooler passages (scale in seawater coolers or dust in air coolers), or a degraded oil filter causing low oil circulation to the rotor profiles.

Can the Tamrotor E12 (50553344) run on both 50 Hz and 60 Hz electrical supplies?

Yes. The air end is rated for variable operational speeds between 1,450 and 6,000 RPM. When swapping between 50 Hz (1,450 RPM synchronous 4-pole) and 60 Hz (1,750 RPM synchronous 4-pole) ship networks, the pulley ratio or gear drive must be verified to ensure the rotor speed remains within the designated flow and power curve.

What is the service interval for the air/oil separator cartridge on this model?

Under standard marine ambient conditions using full synthetic lubricant, the spin-on air/oil separator should be renewed every 2,000 to 4,000 running hours, or whenever the differential pressure across the separator exceeds 0.8 bar (12 psi).

Does this compressor package include automatic unloader valve controls?

The Tamrotor E12 is equipped with an intake unloader valve operated via a solenoid valve. When the discharge receiver reaches the preset cut-out pressure, the intake valve shuts and internal pressure vents down to reduce no-load motor power consumption.

Are full replacement seal kits and bearings available off the shelf for MPN 50553344?

Yes, standard preventative maintenance kits (oil filter, air filter element, separator, unloader seal kit, and minimum pressure valve repair kit) as well as complete bearing overhaul kits are stocked for immediate worldwide marine dispatch.
