Do all capacitors have vents?
Some (electrolytic) capacitors I have in a kit have vents, some do not (not on the top, not on the bottom). The vents are there to safely let the gas out instead of letting the capacitor shoot. So why don't all the capacitors have these? If they would fail (you never know): aren't the vented capacitors safer to use?
What is a minimum ventilation & IAQ standard?
The standard provides procedures and methods for meeting minimum ventilation and IAQ requirements to engineers, design professionals, owners, and jurisdictional authorities where model codes have been adopted.
What are the requirements for a natural ventilation system?
Natural ventilation systems shall comply with the requirements of either Section 6.4.1 or 6.4.2. Designers shall provide interior air barriers, insu- cooled surfaces. 6.4.1 Prescriptive Compliance Path. Any zone designed for natural ventilation shall or both.
Do small electrolytic capacitors have vents?
Yes, the smaller value capacitors, older types (when doing this was not so common), Axial shaped capacitors (wires coming out on opposite sites). I have plenty in my parts drawer which do not have the weakened top. Mar 9, 2017 at 20:29 Small electrolytic capacitors (diameter 5 and 6.3 mm) usually don't have vents because:
Why do capacitors have vents?
Actually these vents are not vents but a deliberately made weak-point in the housing of the capacitor. The vents are only needed for Capacitors which contain some electrolytic fluid which could start to boil and create pressure. Not all capacitors contain electrolytic fluid, for example "Solid electrolytic capacitors" or "Polymer capacitors" don't.
What does 'ventilation and acceptable indoor air quality' mean?
To signify that indoor air quality goes beyond minimum ventilation requirements—and in recognition of those aspects of building systems (equipment, filtration, controls, and more) that contribute to acceptable IAQ—the title of the standard has been updated to “Ventilation and Acceptable Indoor Air Quality.”

Wiring Diagram: Capacitor-Enhanced Exhaust Fan
Capacitor in Exhaust Fan Wiring: In an exhaust fan circuit, a capacitor is often used to provide the starting torque required for the motor to start and overcome inertia. It helps in getting the fan blades up to speed quickly. The capacitor is connected in series with the motor windings and provides a phase shift that creates the necessary torque.
