Frequently Asked Questions

What is the Anden AS35AFP Steam Humidifier and who is it designed for?

The Anden AS35AFP is a medium-capacity commercial steam humidifier delivering up to 277 pints of moisture per day. It is designed for indoor cultivation facilities — including grow rooms, greenhouses, and controlled-environment agriculture (CEA) operations — where consistent, precise humidity control is essential for plant health and yield. The integrated fan pack enables ductless installation, making it a versatile choice for a wide range of facility configurations. It is ideal for operations that need more capacity than a small unit but don’t require the full output of the AS150.

Does the AS35AFP require ductwork or a separate HVAC connection?

The AS35AFP includes a built-in fan pack that allows for ductless installation. Steam is distributed directly into the grow space without the need for dedicated ductwork. The fan pack can be mounted at canopy height for optimal distribution. However, installation by a local HVAC professional is recommended to ensure proper plumbing connections for the drain and fill lines.

How does the AS35AFP handle maintenance and canister replacement?

Maintenance is straightforward — no cleaning or scrubbing of the canister is required. When the factory-installed steam canister reaches end-of-life, simply remove and replace it. The unit’s operating time monitor tracks canister life and activates service notifications so you always know when a replacement is needed. The automatic drain and fill cycle also keeps the system running at optimal conductivity between canister changes.

What controls and monitoring options are included with the AS35AFP?

The AS35AFP includes the Model 5558 A65 Humidistat Controller for dedicated humidity monitoring and control. The display panel provides on/off operation and illuminated LEDs showing fill, drain, steam operations, and diagnostics. The internal control board manages all operational functions automatically, including water level, drain cycles, and end-of-season drain — minimizing the need for manual intervention.
