When the lead acid battery is charged, sulfuric acid in the electrolyte keeps increasing, water gradually decreases, and the specific gravity of the solution rises.

A powered air purifying respirator (PAPR) is a portable battery-powered air filtration system. The system filters out contaminants and particulates in the immediate environment to provide the user with clean filtered air, which is then powered through a breathing tube connected to a loose or tight-fitting respirator. For more information read our blog post about PAPRs.

One not-so-nice feature of lead acid batteries is that they discharge all by themselves, even if not in use. A general rule of thumb is a one per cent per day self-discharge rate. This rate increases at high temperatures and decreases at colder temperatures.

The RPB PX5 is a compact and versatile PAPR that changes the way people experience clean filtered air across multiple industries. Rated to IP65 in use and IP67 with cleaning kit in place, the PX5 has been engineered with a completely sealed housing unit and smooth, considered surfaces for ease of decontamination.

Commonly used in the manufacturing industry, PAPRs are suitable for any working environment where unrestricted movement is essential, and eye, face, or hearing protection is required. Combining multiple forms of PPE into the one system makes PAPRs ideal for not only industrial workplaces, but also healthcare settings too. With complete portability, experience an uncompromised range of movement while receiving clean, filtered air with a PAPR.

If you’re new to respiratory protection or just want to know a bit more, then this webinar is perfect for you. We discuss how loose-fitting respirators work and the benefits of using this type of protection.

Charging is a process that reverses the electrochemical reaction. It converts the electrical energy from the charger into chemical energy in the battery. However, a battery does not store electricity; it keeps the chemical energy necessary to produce electricity.

When the lead battery is discharged, the sulfuric acid in the electrolyte decreases continuously, the water increases gradually, and the specific gravity of the solution falls.

Rated to IP65 in use and IP67 with cleaning kit in place, the PX5 has been engineered with a completely sealed housing unit and smooth, considered surfaces for ease of decontamination.

The lead acid storage battery is formed by dipping the lead peroxide plate and sponge lead plate in dilute sulfuric acid. An electric current is connected externally between these plates. In diluted sulfuric acid, the acid molecules split into positive hydrogen ions (H+) and negative sulfate ions (SO4 − −). When it reaches the PbO2 plate, the hydrogen ions receive electrons from it and become hydrogen atom which again attacks PbO2 and forms PbO and H2O (water). This PbO reacts with H2 SO4 and forms PbSO4 and H2O (water).

A lead acid battery is a rechargeable battery that uses lead and sulphuric acid to function. The lead is submerged into the sulphuric acid to allow a controlled chemical reaction.

PAPRs are a positive pressure respirator. They enable the user to breathe as they normally would as the air supply is propelled into the user's breathe zone via its fan. This innovative approach enables an advanced level of respiratory protection as the HEPA filters utilized for PAPRs offer a greater filtration capacity than those of a negative pressure respirator. The result is a safer, more comfortable, and more productive team.

SO4− − ions (anions) move towards the electrode (anode) connected with the positive terminal of the DC source, where they will give up their extra electrons and become radical SO4. This radical SO4 cannot exist alone; hence reacts with PbSO4 of anode and forms lead peroxide (PbO2) and sulfuric acid (H2SO4).

A battery charger reverses the current flow, providing that the charger has a greater voltage than the battery. The charger creates an excess of electrons at the negative plates, and the positive hydrogen ions are attracted to them. The hydrogen reacts with the lead sulfate to form sulfuric acid and lead, and when most of the sulfate is gone, hydrogen rises from the negative plates. The oxygen in the water reacts with the lead sulfate on the positive plates to turn them again into lead dioxide, and oxygen bubbles rise from the positive plates when the reaction is almost complete. This is called gassing.
