Carbon Active EC Silent Box

Difference between AC, EC & TC fans

🔌 AC fans (AC = Alternating Current)

The robust classic
AC fans operate with classic alternating current motors. They are reliable, durable, and attractively priced.
Advantages
Affordable purchase price
Very robust & durable
Simple technology, not very prone to malfunctions
Disadvantages
Higher electricity consumption
Louder in performance regulation
Speed ​​control is only practical with an external step-down transformer.
Typical application
Standard grow boxes
Exhaust systems without fine-tuning
Users focusing on price & robustness

⚡ EC fans (EC = Electronically Commutated)

The modern, efficient solution
EC fans use brushless DC motors with integrated electronics. They are extremely efficient, quiet, and precisely controllable.
Advantages
Very high efficiency (up to 50% energy savings)
Extremely quiet – even under partial load
Continuously adjustable (0–100%)
Long service life
Disadvantages
Higher purchase price
Typical application
Professional grow setups
Continuous operation
Energy-efficient & quiet systems
CO₂ setups & precise climate control

🌡️ TC fans (TC = Temperature Controlled)

The automatically controlled comfort fan
TC fans are mostly based on AC technology, but have an integrated temperature sensor that automatically adjusts the speed.
Advantages
Automatic temperature control
No external control unit required
Easy to use
Disadvantages
Less precise than EC
Slightly louder than EC
Lower energy efficiency
Typical application
Beginner grow boxes
Users who want "plug & play"
Rooms with fluctuating temperatures

Quiet & vibration-free: Soundproofed with melamine foam – virtually noiseless in operation.
Adjustable & efficient: Speed ​​can be reduced to 10%, without humming noise.
Compact & powerful: Optimized size/airflow ratio for high efficiency
High pressure & low power consumption: EC technology with strong Pa value and energy savings
Easy assembly: Small footprint, cost-effective installation
Plug & Play: Compatible with all CarbonActive EC Digital Controllers
Universal application: Ideal for exhaust systems in grow boxes, industrial and residential spaces
Note: EC fans can only be operated with a controller.
