IA Inlet Actuator

Manual for use and Maintenance

Thank You:

Thank you for purchasing a Munters IA Inlet Actuator. Munters equipment is designed to be the highest performing,
highest quality equipment you can buy. With the proper installation and maintenance it will provide many years
of service.

Description:

The IA0090/IA0250D motor gearbox is a maintenance-free, compact drive unit for accurately opening and
closing air inlet flaps, air valves and ventilation curtains in livestock houses and crop storage buildings.

The IA0090/IA0250D motor gearbox features a self-braking worm gear transmission. This transmission ensures
that the drive shaft is not rotatable when the drive unit is stopped. The combination of carefully matched pinion and
worm reductions results in a quiet mechanical transmission.

The IA0090/IA0250D motor gearboxes feature a power switching integrated linear limit switch system with duty
and safety switches with an excellent switching precision of the end positions. The maximum switching range of the
limit switch system equates to 55 revolutions of the drive shaft. With use of an optional potentiometer built-in set, it
is possible to precisely feedback intermediate and end positions to a (climate) computer.

The IA0090/IA0250D motor gearboxes are finished with a blue powder coating and are supplied including
mounting bolts and spring washers.

IA0090 motor gearboxes: IA0250D motor gearboxes:

• Drive torques of 1000 lb.-in.; • Drive torques of 3540 lb.-in.;

• 1.2 at 60 Hz mains frequency; • 1.2 at 60 Hz mains frequency;

Suitable for intermittent use, duty class 3-30%, duty cycle maximum 25 minutes;
Provided with a two-sided output drive shaft for mounting one winch or belt drum or two 16-tooth

1/2”x5/16” zinc-plated sprockets for chain couplings;

• Manual drive enabled by means of a hexagon socket in electric motor shaft;

• Electric motors are standard tropic-proof and conform to protection class IP55;

• Available as 1-phase 115 V (60 Hz) electric motor with UL and CSA approval.

Please Note:

To achieve maximum performance and insure long life from your Munters product it is essential that it be installed
and maintained properly. Please read all instructions carefully before beginning installation.
