FAQ
1. How do I clean or maintain the fan? Do I need to remove the ceiling if it breaks?
No ceiling dismantling is required! The decorative front panel is easily removable for quick cleaning. To access the fan motor or internal components, simply unsnap the locking ring. If the motor ever needs servicing or replacement in the future, the core unit can be extracted directly through the existing opening without touching the stretch canvas.
2. How does the fan connect to the ventilation duct?
To achieve its ultra-low profile, the Gratka Slim is designed to connect directly into a standard flat rectangular plastic duct (60x204 mm). This direct connection eliminates the need for bulky round-to-flat adapters, which is exactly how the fan maintains its minimal mounting depth.
3. What type of motor is used inside? Is it reliable?
We use premium European-made motors from the renowned Bulgarian manufacturer, MMPmotors. These high-quality ball-bearing engines are specifically engineered for continuous operation, exceptional durability, and ultra-quiet performance.
4. What is the warranty on the Gratka Slim?
We stand completely behind the quality of our product and provide a full 3-year official manufacturer's warranty on the motor.
5. Is it safe to install directly above a shower or bathtub?
Yes, absolutely. The Gratka Slim features an IP44 protection rating, which means it is fully protected against water splashes from any direction, making it safe for bathroom zones.

Ultra-Low Profile

Maximize your room height with our shallow depth extractor fan. The Gratka Slim requires a minimum ceiling void of just 110 mm, delivering powerful hidden ventilation without the bulk.

Upgrade Your Interior

See the difference. Standard extractor fans draw unwanted attention, accumulate dust, and ruin expensive stretch ceilings over time. The Gratka Slim changes everything.

❌ Moisture Damage & Risk

Standard fans lack proper waterproofing, making them unsafe to install directly above showers and leading to mold growth over time.

✅ Ultimate Moisture Protection

With an IP44 waterproof rating and up to 150 m³/h airflow, it swiftly eliminates steam and is 100% safe for wet bathroom zones.

❌ Maintenance Risks

Hard to clean grilles. Removing them risks tearing your expensive stretch ceiling canvas.

✅ Safe & Easy

Magnetic front panel and a smart locking ring allow instant cleaning with zero risk to your ceiling.

❌ Standard Fans

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

✅ Gratka Slim

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

❌ Lost Ceiling Height

Deep standard fans and bulky round adapters force you to lower your entire stretch ceiling, stealing valuable room space.

✅ Maximum Room Height

Requires only a 90mm ceiling void. It connects directly to flat rectangular ducts to perfectly preserve your ceiling height.

How It Works

The quick-release magnetic panel and protective locking ring mean you can clean or replace the fan motor anytime. Full access, zero risk to your stretch ceiling.
