ANAVI Fume Extractor is a smart, open source, solder smoke absorber. It is powered by a Wi-Fi development board with an ESP8266, an 80 mm fan, and a replaceable filter. ANAVI Fume Extractor has dedicated slots for a mini OLED I²C display and a MQ-135 gas sensor module, as well as slots for up to three additional I²C sensor modules for measuring temperature, humidity, light, and barometric pressure. Furthermore, there are UART pins for easy flashing of custom firmware and an extra GPIO for connecting external peripherals.

Soldering is fun, but soldering fumes are dangerous to your health. Stay safe and healthy by using a fume extractor. Existing products on the market are bulky, noisy, and lack smart features. The alternative is ANAVI Fume Extractor!

ANAVI Fume Extractor comes as a do-it-yourself (DIY) kit that combines open source hardware with free and open source software. Its design is based on experience from our previous open source hardware products and community feedback. ANAVI Fume Extractor is lightweight and can even be portable with a USB power bank. The filters and all parts are replaceable. Each kit includes two filters. For long-term maintenance you can purchase extra 80 mm, 45 PPI foam media filters from Mouser or other distributors of electronic components.

The default open source firmware allows you to connect ANAVI Fume Extractor to your Wi-Fi network to gather data from various sensors and control it remotely. Through the lightweight messaging protocol MQTT ANAVI Fume Extractor works with popular open source home automation software tools such as Home Assistant, OpenHAB, and ioBroker.

All these features make ANAVI Fume Extractor a must-have tool for any maker, do-it-yourself-er (DIY), and open source enthusiast!

Quick Setup

You don’t need to be a tech whiz to use ANAVI Fume Extractor. Getting started is easy. All you need to assemble it is a screwdriver. Whether you’re a newbie to soldering or a skilled maker, ANAVI Fume Extractor is a great choice for your projects.

ANAVI Fume Extractor can also serve as a convenient development board for home automation projects that’s suitable for anyone interested in Internet of Things, coding, and open source. We will provide a comprehensive user’s manual with exact steps for using all the features of ANAVI Fume Extractor.

ANAVI Fume Extractor can be used in offline or online mode by connecting it to your local Wi-Fi network and MQTT broker for integration with open source IoT platforms. When turning Wi-Fi on for the very first time, it will create Wi-Fi Access Point (AP) with a captive portal for user-friendly initial configuration from a personal computer, smartphone or a tablet.

Proudly Open Source

ANAVI Fume Extractor is an entirely open source project that combines open source hardware with free and open source software. It has been certified by the Open Source Hardware Association under UID BG000060.

ANAVI Fume Extractor relies upon community-supported free and open source software tools. KiCad and OpenSCAD were used to design the printed circuit board and the acrylic enclosure. The default firmware is an Arduino sketch. Source code and schematics are available on GitHub.

There are literally hundreds of existing fume extractors for home usage on the market, but most of them are bulky, noisy and without any smart features. Existing do-it-yourself alternatives are either difficult to build and/or not fully open source. ANAVI Fume Extractor is not like them!

Unlike the rest, ANAVI Fume Extractor is entirely open source, supports a huge variety of peripheral sensor modules, and works out of the box with popular platforms for Internet of Things (like Home Assistant) through the machine-to-machine protocol MQTT.

ANAVI Fume Extractor uses off the shelf replaceable parts. The device can be easily repaired or modified so it can serve you well for years!

Manufacturing Plan

To ensure consistently high quality, the printed circuit board (PCB) of ANAVI Fume Extractor has a green solder mask and a gold surface finish. All PCBs will be manufactured and assembled at a local factory in Plovdiv, Bulgaria, EU. Boards will be carefully manually flashed and tested with open source software already available at GitHub as an Arduino sketch.

Shipping & Fulfillment

All units of ANAVI Fume Extractor will be shipped to our backers using Crowd Supply’s fulfillment services. Once manufacturing is complete, we’ll make a bulk shipment to Crowd Supply and from there, the packages will be shipped out to our individual backers. For more details, please have a look at this guide to ordering, paying, and shipping.

Risks & Challenges

ANAVI Fume Extractor is a certified open source hardware product. We have been developing it for more than six months and we already have manufactured a small-run batch to ensure that everything works correctly. Although this significantly reduces any risks, mass production still depends on factories and suppliers. Availability of parts can also be an issue. In order to provide ANAVI Fume Extractor at the best price, we are working with reliable suppliers and a trusted local factory in Plovdiv, Bulgaria.

We have experience successfully delivering projects on time, and even ahead of schedule, from our previous crowdfunding campaigns for ANAVI Thermometer, ANAVI Gas Detector, ANAVI Infrared pHAT, ANAVI Miracle Controller, ANAVI Light Controller, and many more. This time, due to the COVID-19 outbreak, we are facing completely new challenges. Suppliers and factories are working with reduced capacity, therefore, we have set estimated shipping dates far out in the future. In case of a complete inability to deliver, or with some kind of shipping failure, Crowd Supply will offer backers full refunds. If any delays occur, backers will be notified promptly through regular updates.

Stretch Goals

Our crowdfunding campaign has a very modest goal of just $1, but if we raise:

In the Press

Hackster News

"Breathing solder smoke (or flux) can be hazardous to your health, and just like spray painting, it's best to have some kind of airflow to dissipate those fumes. ANAVI Technology has designed a small smoke absorber to help capture those solder fumes"

PCBWay Community Blog

"ANAVI Fume Extractor comes as a DIY kit. Don’t worry, it is quite easy to assemble."

Geeky Gadgets

"The ANAVI Fume Extractor has a dedicated slots for a mini OLED I²C display and MQ-135 gas sensor module as well as slots up to 3 additional I²C sensor modules."

CNX Software

"If you are only going to use the platform as a fume extractor, there’s no need for network connectivity, and there’s a jumper that will disable WiFi."


""Iniciando en breve su proceso de crowdfunding, esta máquina de soldadura por fase de vapor es más versátil que aquellas que emplean otros métodos.""



"Un extracteur de fumées est un ajout indispensable à toute panoplie d’électronicien. La pratique de la soudure ayant rarement lieu à l’extérieur, il faut éviter le plus possible de respirer les émanations de vos opérations."
