Humidity Sensor with Timer

The fan continuously monitors the humidity level in the room, operating completely automatically to keep your space dry and mold-free.

  • 💧 Smart Humidity Trigger When humidity reaches your pre-set threshold (adjustable from 40% to 80%), the sensor immediately starts the fan to extract steam.
  • ⏱️ Automatic Run-on Timer When the humidity drops back to a normal level, the timer keeps the fan running for 3 to 23 minutes (adjustable) to ensure perfect ventilation, after which it turns itself off.

How it works

Flush Mount

Flawless minimalism. The device is mounted flush with the surface, leaving only an elegant shadow gap visible for air intake.

Invisible Panel

The metal tray is designed for absolute invisibility. Insert porcelain stoneware, MDF, or drywall inside, and paint it to perfectly match your finish.

Magnetic Fixation

4 powerful neodymium magnets with threading and fine height adjustment ensure perfect, millimeter-precise panel alignment. Withstanding up to 15 kg of shear force, they are absolutely reliable and safe.

Independent Mounting

The fan is secured to the base with independent bolts. This allows you to easily remove the motor unit for cleaning or maintenance without dismantling the entire structure.

The Heart of the System

The core of the exhaust fan is a powerful and silent European motor, engineered for years of continuous, flawless operation.

Upgrade Your Interior

Standard extractor fans draw unwanted attention, accumulate dust rings, and ruin the flawless look of your premium porcelain stoneware and drywall finishes. The Gratka Hide invisible exhaust fan changes everything.

❌ Cheap Plastic & Bare Metal

Cheap plastic discolors, and untreated metal inevitably rusts in high-humidity environments like bathrooms, completely ruining your premium finish.

✅ Galvanized & Powder-Coated

Built from galvanized steel with a premium powder-coated finish. This double armor provides 100% corrosion resistance, ensuring your extractor fan looks flawless for decades, even in the wettest conditions.

❌ Maintenance Risks

Hard to clean grilles. Removing them risks chipping the paint or cracking the plaster on your pristine drywall ceiling.

✅ Safe & Easy

Simply remove the magnetic metal panel for instant cleaning, with zero risk to your finish.

❌ Standard Fans

Bulky plastic covers that stick out, turn yellow over time, and ruin your modern design.

✅ Gratka Hide

Perfectly hidden, flush-mounted design that blends seamlessly into any premium interior.

❌ Noise & Vibration

Flimsy plastic housings transfer motor vibrations directly to the ceiling, amplifying the annoying hum.

✅ Absolute Silence

The heavy steel base and anti-vibration mounts absorb all resonance. No rattling — just the whisper of moving air.
