Compact Powerhouse: KNOKOO FES150D — A Precise Fume-Extraction Solution for Small Workspaces

Solder fumes at electronics repair stations, fine particulate dust from laser engraving, and VOC odors generated during 3D printing… In confined working areas, these fumes and odors not only pose health risks but also compromise operational accuracy and product quality. Traditional fume extractors are often too bulky, occupy valuable space, or require complex duct installation, making them unsuitable for compact environments.
The KNOKOO FES150D, built around a “mini form factor + high-efficiency purification” concept, is engineered specifically for small workspaces—providing targeted, high-performance extraction for electronics repair, laser processing, 3D printing and more, enabling clean and efficient production with ease.

1. Compact & Convenient Design — Perfect Fit with Zero Space Burden

Designed with the unique needs of small work areas in mind, the FES150D balances practicality and ease of use in every detail.

Mini Body, No Space Wasted

Its integrated metal frame and high-quality cold-rolled steel housing with electrostatic powder coating ensure durability and a clean, modern appearance. The compact footprint allows the unit to sit beside an electronics repair bench, next to a laser engraver, in a 3D printing corner, or even inside narrow workstation gaps—without disturbing workflow or taking up valuable workspace.

No Installation Required + Easy Mobility

The FES150D requires no additional ducting or professional installation. Simply adjust the fume arm and the unit is ready to operate—saving both setup time and installation cost. Lightweight construction allows one person to move it easily between workstations, ideal for small areas requiring flexible deployment.

User-Friendly Controls, Ready Out of the Box

Equipped with an LED display for real-time airflow visualization, the operator can clearly see performance at a glance. The stepless speed controller and ergonomic knobs allow precise adjustment based on fume intensity—whether handling light solder fumes or sudden bursts of laser dust—without any training required.

Aerodynamic Air Inlet for Enhanced Capture

The specially curved inlet flange follows fluid dynamics principles to minimize airflow resistance and increase capture efficiency. Even dispersed fumes in a small space can be quickly drawn in and filtered.

2. Advanced Power System — Low Noise, Energy Efficient & Long-Life

Small workspaces require a careful balance of strong suction, low noise, and low energy consumption. The FES150D’s drive system is engineered precisely for that balance.

DC Brushless Motor — Stable, Quiet, Non-Disruptive

With a built-in controller, the DC brushless motor runs smoothly with significantly lower noise compared to traditional motors. It maintains a quiet environment for precision electronics repair, laser engraving, or 3D printing operations—ensuring clean air without compromising concentration or comfort.

High Airflow & Strong Suction — Instant Removal of Dense Fumes

The backward-curved turbine impeller made from special alloy material resists fume corrosion and is calibrated with dynamic balancing technology for smooth, vibration-free operation. It delivers powerful airflow to rapidly remove concentrated fumes in tight spaces. Filtration efficiency is 25% higher than standard mini extractors, preventing smoke stagnation around work surfaces.

Maintenance-Free & Energy-Saving

The motor requires no periodic servicing, reducing downtime and maintenance cost—ideal for long-hours operation in studios or workshops. Energy-efficient design cuts electricity consumption by up to 40% compared to conventional equipment, making it especially suitable for cost-sensitive small businesses.

3. Four-Stage Deep Filtration — 99.99% Purification with No Blind Spots

In small areas, fumes tend to accumulate and contain complex particles. The FES150D’s multi-layer filtration system ensures thorough purification while meeting global environmental standards.

Four-Stage Progressive Filtration

• Pre-filter traps solder splashes, plastic debris, and large particles—extending the life of subsequent filters.

• Medium filter captures sub-micron particulate matter down to 0.3 µm, such as soldering tin dust or laser-engraved metal powder.

• High-efficiency filter removes remaining ultra-fine particulates.

• Internal adsorption layer simultaneously eliminates VOCs and odors from solder flux and printing materials.

The system achieves up to 99.99% purification efficiency, meeting environmental requirements such as CE (EU) and EPA (US) standards, enabling easy compliance with air-quality audits.

Sealed Filtration Path — Zero Leakage, No Secondary Pollution

A reinforced internal sealing structure ensures 100% of collected fumes pass through the filtration system, preventing bypass or leakage—maintaining clean, stable air quality even in enclosed work environments.

Internal Air Recirculation — Does Not Affect Temperature-Sensitive Processes

The internal closed-loop circulation design prevents loss of conditioned indoor air. This is critical in processes requiring stable temperature and humidity—such as electronics soldering or high-precision 3D printing—ensuring consistent production quality while purifying the air.

Modular Filters — Lower Replacement Cost, Longer Service Life

Pre-filters, medium filters, and HEPA filters can be replaced individually rather than as a single block. For example, in soldering applications where the pre-filter clogs faster, only that layer needs replacement. This extends the life of the main filters and reduces consumable cost by over 30% versus conventional all-in-one cartridges.

4. Precision Capture & Multi-Scenario Compatibility — Full Coverage for Small Spaces

The FES150D’s extraction system ensures fumes are captured directly at the source, preventing workplace contamination.

Flexible Fume Arm — Targeted Source Capture

The multi-directional fume arm positions freely and locks into place, allowing precise extraction from soldering irons, laser heads, or 3D printer nozzles. Customizable arm lengths support unique space requirements—achieving true “point-to-point” source capture.

New-Design Capture Hood — Expanded Coverage Area

The redesigned hood increases the effective capture zone by 30% compared to traditional models. Even lightly drifting fumes are pulled in instantly, further supported by the aerodynamic inlet structure for maximum efficiency.

Optimized for Multiple Small-Space Applications

• Electronics repair (mobile/PCB repair): Captures solder smoke and flux odor without occupying workbench space.

• Laser engraving/marking: Removes fine metal particles and dense smoke, prevents lens contamination, and operates quietly.

• 3D printing: Efficiently adsorbs VOCs and fumes from ABS, nylon, and other materials; internal circulation maintains stable print-chamber temperature.

• Other uses: Nail studios, small grinding stations, and other dust- or odor-producing environments.

5. Why Choose FES150D — Professional-Grade Purification for Compact Areas

For small-space users, the KNOKOO FES150D is not a “makeshift” option—it is the most precisely engineered, productivity-enhancing solution available.
It solves the challenges of limited space, high installation costs, insufficient purification, and high operating expenses through:

• Mini size for easy placement

• No-installation setup for quick deployment

• Four-stage filtration for thorough purification

• Low-noise, low-energy operation for cost-effective long-term use

Whether in personal studios, small manufacturing workshops, or mobile workstations, the FES150D delivers big-machine performance in a compact body—protecting worker health, ensuring compliance, and improving production efficiency.
