Anden AS150 High-Capacity Steam Humidifier Built-In Fan Pack

Electrode Steam Humidification for Large Facilities, Up to 24,000 Sq Ft

Propagation and early vegetative growth stall out fast when relative humidity drops below what cuttings and young plants need, and a fogger or ultrasonic humidifier sized for a home grow tent runs out of capacity long before it covers a commercial-scale room. Anden's electrode steam humidifiers are built for that larger scale, generating steam directly from an electrode canister rather than atomizing water, and distributing it through a fan pack sized to the space.

The AS150 is Anden's high-capacity steam humidifier, adding up to 1,200 pints (150 gallons) of moisture per day for spaces up to 24,000 square feet. Its built-in fan pack and Vapor-Logic control give facility-scale rooms the same precision humidity management as the smaller AS35FP, scaled up to cover far more square footage from a single unit.

Key Features & Benefits

• Up to 1,200 Pints (150 Gal) per Day — Covers spaces up to 24,000 square feet from a single unit.
• Built-In Fan Pack — Distributes steam across a large room without a separate fan accessory.
• Vapor-Logic Control — Precision humidity management tuned for large, facility-scale spaces.
• High-Capacity Electrode Design — Scales Anden's electrode steam mechanism up to cover far more square footage than the AS35FP.
• Professional Installation Required — Ties into electrical and water service, so plan for a licensed HVAC installer.

Who Should Use This Steam Humidifier

This unit fits commercial cultivation facilities and large propagation rooms where humidity needs to stay in a tight, precise range across a wide floor area — not a single grow tent or small home setup. Anden's steam humidifiers require professional HVAC installation, so plan for a licensed installer as part of bringing one of these online.

How Anden's Electrode Steam Humidifiers Work

Anden's steam humidifiers pass an electric current through water inside a replaceable canister, boiling it to generate steam directly rather than misting or atomizing water droplets. That steam is distributed into the space through a fan pack, giving more precise, even humidity control across a large room than atomizing methods typically achieve. Because the canister mineralizes as it boils water, it's a scheduled replacement part rather than a permanent component.

Frequently Asked Questions

How much moisture does the AS150 add per day?

The AS150 adds up to 1,200 pints, or roughly 150 gallons, of moisture per day. That's Anden's highest-capacity steam humidifier, built to cover spaces up to 24,000 square feet from a single unit.

Why does this need professional installation?

Anden's steam humidifiers tie into electrical service and often building HVAC or duct systems, which puts installation outside typical DIY electrical work. A licensed HVAC professional can also properly size the water supply and drain connections a unit this large needs to run reliably.

How does electrode steam humidification differ from a fogger or ultrasonic humidifier?

Electrode steam humidifiers boil water using an electric current run through the water itself, generating true steam rather than atomizing water into a fine mist. That approach scales to large facility spaces and delivers more consistent humidity than fogger or ultrasonic units designed for smaller rooms.

What maintenance does the AS150's canister need?

The AS150 uses a cylinder and canister kit (DH5872) that needs periodic replacement once mineral deposits on the electrodes reduce steam output. Follow Anden's installation instructions for canister replacement to keep output consistent.

What is Vapor-Logic control?

Vapor-Logic is the AS150's control system for managing precision humidity output at facility scale, adjusting steam generation to match the room's actual demand rather than running at a fixed rate. That precision matters more as room size and airflow variability increase.
